## Title
Methods for extending a document transformation server to process multiple documents from multiple sites and devices thereof

## Abstract

A method, computer readable medium and device that extends a document transformation server to process multiple documents from multiple websites includes obtaining with a document transformation server a document to process based on at least a URL of the document to process in an HTTP request URL. An XML source representing the document to process is generated with the document transformation server. One or more XML processors associated with at least a portion of the HTTP request URL from a plurality of stored associations are identified with the document transformation server. The XML source is transformed by the document transformation server with each of the identified one identified XML processors. The generated document is provided in an HTTP response to the HTTP request URL by the document transformation server.

## Background
FIELD
This technology generally relates to methods and devices for transforming and rendering documents and, more particularly, to methods for extending a document transformation server to process multiple documents from multiple sites and devices thereof.
BACKGROUND
The introduction of eXtensible Markup Language (XML) and the EXtensibleStylesheet Language (XSL) specifications has provided an easy way to transform documents between various formats. This functionality has been included into Web development frameworks enabling them to automatically transform an XML file into a document with different format, such as HTML or XHTML, and integrate the original data with a graphic layout and user interface parts.
This transformation process is based on the following basic scheme. Each URL on a website is associated to a single XML file and to one or more XSL style sheets. The associated XML file and XSL style sheet(s) include the transformation rules used to customize the webpage into a desired format.
An example of a prior art method for transforming and rendering a single document is illustrated in FIG. 2. In step 100, a server receives an HTTP request. In step 102, the server extracts the parts from the PATH and QUERY fields in the HTTP request to identify and obtain the document to be processed.
In step 104, the server determines whether the extracted parts in the PATH and QUERY fields of the HTTP request match an XML source for the document to be processed. If in step 104 the server determines the extracted parts in the PATH and QUERY fields of the HTTP request do not have an association with an XML source, then the No branch is taken to step 106. In step 106, the server generates an error page document. In step 108 the server returns the generated error page document in an HTTP response to the HTTP request.
If in step 104 the server determines the extracted parts in the PATH and QUERY fields of the HTTP request do have an association with an XML source for the document to be processed, then the Yes branch is taken to step 110. In step 110, the server obtains the document to be processed from the XML source and generates an XML document.
In step 112, the server determines whether the extracted parts in the PATH and QUERY fields of the HTTP request match one of one or more stored XML processors. If in step 112 the server determines the extracted parts in the PATH and QUERY fields of the HTTP request do not match one of one or more stored XML processors, then the No branch is taken to step 114. In step 114, the server converts the XML document into a desired format. Next, in step 108 the returns the converted XML document in an HTTP response to the HTTP request.
If in step 112 the server determines the extracted parts in the PATH and QUERY fields of the HTTP request do match one or more stored of the XML processors, then the Yes branch is taken to step 116. In step 116, the server runs the one or more matching XML processors on the previously generated XML document. In step 114, the server converts the processed XML document into a desired format. Next, in step 108 the server returns the converted XML document in an HTTP response to the HTTP request.
Referring to FIG. 3, an exemplary prior art fragment of a sitemap.xmap document which is a configuration file of Apache Cocoon is illustrated. This fragment has two sets of prior art instructions to process documents.
The first set of instructions executed starts with XML element <map:match pattern=””> and matches the document with an empty component in the PATH field that is the home page of a site (for example www.sample.com). The document is obtained by loading the XML file “welcome.xml” as the document or other file to be processed, then applying the XSL transformation described in welcome.xsl using XHTML format to return it to the browser because of the <map:serialize> instruction.
The second set of instructions matches an entire set of web site pages: all pages whose PATH field starts with “static-site/” and ends with a name followed by “.xml” extension (for example, www.sample.com/static-site/news.xml). The first instruction loads the corresponding documents or other files from the xdocs directory (for example xdocs/news.xml). The second instruction applies an XSL transformation using one or more identified matching XML processors that transforms the original xml document into an HTML document adding web site user interface (web site navigation links, site logo etc). The last instruction returns the document to the browser in HTML format.
Accordingly, as illustrated and described above, the prior art provides methods for transforming and rendering documents. Unfortunately, these transformation rules currently can not be utilized in an effective and efficient manner by a document transformation server in a single application instance to transform multiple documents from multiple websites.

An exemplary method for extending a document transformation server 12 to process multiple documents from multiple sites, such as web server devices 16(1)-16(n), in an exemplary environment 10 will now be described with reference to FIGS. 1 and 4-6. Referring more specifically to FIG. 4, in step 200 the document transformation server 12 receives an HTTP request whose url contains the URI of the document to process, from one of the client computing devices 14(1)-14(n), although other types of requests could be received and from other types of devices. Optionally, if the URI of the document to process is encoded, the document transformation server 12 will decode the URI of the document to process, although other manners for processing an encoded URI or other encoded portion of a URI HTTP request could be used. Since manners for encoding and decoding are well known to those of ordinary skill in the art, they will not be described in detail here. By way of example only, consider an HTTP request from one of the client computing devices 14(1)-14(n) where the URL to be processed is embedded in the PATH field of the HTTP request url: http://processor.com/app/www.acme.com/anyproduct.html. The transformer server applications is identified by “processor.com/app”; the address www.acme.com/anyproduct.html is the resource to be processed.
In step 202, the document transformation server 12 extracts the domain in the URI of the document to process, although other fields of the URI could be extracted and used.
In step 204, the document transformation server 12 determines whether the transformation of the website in the URI of the document to process is allowed. If in step 204, the document transformation server 12 determines the transformation of the website in the URI of the document to process is not allowed, then the No branch is taken to step 206. In step 206, the document transformation server 12 generates an error page document. In step 208 the document transformation server 12 returns the generated error page document in an HTTP response to the one of the client computing devices 14(1)-14(n) that provided the HTTP request in this example.
If in step 204, the document transformation server 12 determines the transformation of the website in the URI of the document to process is allowed, then the Yes branch is taken to step 210. In step 210, the document transformation server 12 downloads the original document or other resource linked by the given URL and transforms the downloaded document into an XML source, although other manners for processing the obtained document or documents can be used. In step 212, document transformation server 12 looks for a mapping or configuration file for the directory that matches the extracted domain. An exemplary method for locating a mapping file from manifest.xml is described herein with reference to FIG. 5.
In step 214, the document transformation server 12 determines whether the mapping file for the extracted domain exists. If in step 214 the document transformation server 12 determines the mapping file does not exist, then the No branch is taken to step 216. In step 216, the document transformation server 12 converts the document into the desired format. Next, in step 208 the document transformation server 12 returns the converted document in an HTTP response to the one of the client computing devices 14(1)-14(n) that provided the HTTP request.
If in step 214 the document transformation server 12 determines the mapping file for the extracted domain does exist, then the Yes branch is taken to step 218. In step 218, the document transformation server 12 use the mapping file to identify all of the XSL processors linked to the corresponding URL and applies the identified XSL processors to the document to be processed.
Optionally the document transformation server 12 may apply one or more best matching rules to filter the identified one or more XML processors in the matching directory. By way of example only, one best matching rule is to take the XML processor with the longest matching pattern string, although other types and numbers of best matching rules can be used.
In step 216, the document transformation server 12 converts the processed document into the desired format. Next, in step 208 the document transformation server returns the converted document in an HTTP response to the one of the client computing devices 14(1)-14(n) that provided the HTTP request.
Referring to FIG. 5, an exemplary method for obtaining a mapping file with the document transformation server 12 is illustrated. In step 300, the document transformation server 12 receives a URI to match from one of the client computing devices 14(1)-14(n), although other types of requests could be received and from other types of devices. In step 302, the document transformation server 12 extracts from the URI the AUTHORITY portion corresponding to the associated domain and port, for example “ssl.example.com:8443”, although other types and numbers of fields could be extracted.
In this example, if the port is either 80 or 443 (default values for HTTP and HTTPS respectively) the string representing the authority corresponds to the domain portion of the URL. However, if the port does not correspond to a standard value, the character is substituted with ‘_’ in order to avoid potential problems in the file system (i.e. ssl.example.com—8443). The string representing the authority is further stripped by the document transformation server 12 removing the ‘www.’ from the extracted string.
In step 304, the document transformation server 12 determines whether there is a directory with the same name as the extracted domain and containing the mapping file, although other manners for determining matches with other portions of the domain can be used. By way of example only, consider the following directories: (1) “www.acme.com”; (2) “_.example.com”; and (3) “ssl.example.com”. The www.acme.com directory will match all the requests for www.acme.com and acme.com domains. With this technology, the “_.example.com” directory will match all the requests for domains ending with “.example.com” that do not have more specific matching directories. Accordingly, “_.example.com” will match “products.example.com”, but it will not match “ssl.example.com” because an “ssl.example.com” directory exists. The “_” character in front of “.example.com” is used to make the directory visible when using file systems that use “.” characters in front of files to hide them to users.
If in step 304 the document transformation server 12 determines there is no directory with the same name as the extracted domain, then the No branch is taken to step 306. In step 306, the document transformation server 12 determines whether the domain contains a valid subdomain. If in step 306 the document transformation server 12 determines the domain does contain a valid subdomain, then the Yes branch is taken to step 308. In step 308, the document transformation server 12 extracts the next level subdomain name and returns to step 304 as described earlier.
If in step 304 the document transformation server 12 determines there is a directory with the same name as the extracted domain and containing the mapping file, then the Yes branch is taken to step 310, although other manners for determining matches with other portions of the domain can be used. In another example, the document transformation server 12 may also use another optional mapping file that stores known aliases of domains. When a known alias of a domain is identified using this optional mapping file, the document transformation server 12 can use the same one or more stored directories for the known and identified aliases. As a result, this reduces the number of stored directories when handling domains with multiple aliases (i.e. defined with DNS records of type CNAME).
In step 310, the document transformation server 12 extracts the parts from the PATH and QUERY fields in the URI, although the parts can be extracted from other types and numbers of fields in the URI.
In step 312, the document transformation server 12 determines whether the extracted parts in the PATH and QUERY fields of the URI match or otherwise have an association with one of one or more XML processors in the identified mapping file, although other types of associations between other types and numbers of parts can be used. If in step 312 the document transformation server 12 determines the extracted parts in the PATH and QUERY fields of the URI match or otherwise have an association with one of one or more XML processors, then the Yes branch is taken to step 314 where the matching XML processors are collected. Next, in step 316, the document transformation server 12 returns the collected XML processors to the requesting one of the client computing devices 14(1)-14(n).
If in step 312 the document transformation server 12 determines the extracted parts in the PATH and QUERY fields of the URI do not match one of one or more XML processors, then the No branch is taken to step 316 where no matching XML processors are returned to the requesting one of the client computing devices 14(1)-14(n).
Referring to FIG. 6, an exemplary implementation of the mapping file “manifest.xml” is illustrated. Each map element identifies an XSL file (inside file element) and a substring to match a URL PATH component (inside the PATH element). The map element with the longest string matching the PATH component will be used to setup the XSL transformer identified by the level attribute.
In these examples, two XSL transformers are defined: level 1 transformer; and level 2 transformer. If the request URL has the PATH field containing “/content/news/july.html”, then the original site web page is downloaded (for example, www.sample.com/content/news/july.html). Next, the level 1 transformer uses the news.xsl stylesheet document to transform the downloaded page. The level 2 transformer uses content2.xsl stylesheet document to transform the document obtained from the level 1 transformer.
If the request URL has the PATH field containing “/content/privacy.html”, then the original site web page is downloaded (for example www.sample.com/content/privacy.html). Next, the level 1 transformer uses the content.xsl stylesheet document to transform the downloaded page. Next, the level 2 transformer uses the content2.xsl stylesheet document to transform the document obtained from the level 1 transformer.
Accordingly, as illustrated and described herein this technology provides a number of advantages including providing a method, computer readable medium and an apparatus that extends a document transformation server to process multiple documents from multiple sites. One of the advantages of this technology is that a single association or match between a name of a directory and at least a portion of a domain name or other part of a URI can be used for hundreds or thousands of URIs. As a result, only a few associations with directories or other stored tables can be enough for the document transformation server to transform the content of an entire website.
Having thus described the basic concept of the invention, it will be rather apparent to those skilled in the art that the foregoing detailed disclosure is intended to be presented by way of example only, and is not limiting. Various alterations, improvements, and modifications will occur and are intended to those skilled in the art, though not expressly stated herein. These alterations, improvements, and modifications are intended to be suggested hereby, and are within the spirit and scope of the invention. Additionally, the recited order of processing elements or sequences, or the use of numbers, letters, or other designations therefore, is not intended to limit the claimed processes to any order except as may be specified in the claims. Accordingly, the invention is limited only by the following claims and equivalents thereto.
