## Title
Method to generate scripts from XML

## Abstract

An XML document can use tags such that scripts can be generated from the documents. The scripts can be start up scripts for different operating systems. For example, the same XML document can be used to produce a UNIX shell script as well as a Windows command file.

## Background
CLAIM OF PRIORITY
This application claims priority to U.S. Provisional Application No. 60/573,270 entitled “Method to Generate Scripts from XML”, filed May 21, 2004.


BACKGROUND OF THE INVENTION
The present invention is directed to the construction of scripts such as start scripts for a server.
SUMMARY OF THE INVENTION
The present invention consists of interpreting tags and information in an XML document to produce a server start script for an operating system, the XML document includes tags which are defined to indicate information such that the XML document can be used to produce server start scripts for multiple types of operating systems; and storing the produced server start script in memory.



BRIEF DESCRIPTION OF THE FIGURES
FIG. 1 is a diagram illustrating the system of the present invention.
FIGS. 2A-2C are diagrams that illustrate graphical user interfaces of one embodiment of the present invention.



DETAILED DESCRIPTION
In one embodiment of the present invention, tags and information in an eXtensible Markup Language (XML) document 102 are interpreted to produce a server start script, such as scripts 104, 106 and 108, for an operating system. The XML document 102 includes tags which are defined to indicate information so that the XML document can be used to produce server start scripts for multiple types of operating systems. Examples of XML tags and constructed script formats of one example is given below in the Script Generator Specification section. The produced server start script, such as scripts 104, 106, and 108, can be stored in memory.
The server start scripts can include UNIX® shell scripts 104, WINDOWSTM command files 106 and other operating system scripts 108. A graphical user interface 110 can be used to produce the XML document. Details of a graphical user interface of one embodiment are described below with respect to FIGS. 2A-2C. The graphical user interface 110 can be used to select the script type. WINDOWSTM and UNIX® are operating systems.
The XML document 102 can be merged with an extension XML document to produce a merged XML document from which the script is produced. The extension XML document can include tags defined for merging XML documents. Such tags can include marker tags, append tags and replace tags.
An Application Programming Interface (API) can be used to create the scripts and/or XML documents. The API allows users to design software that allows for the construction of the scripts and/or XML files.
In one embodiment, the graphical interface 110 is used to produce an intermediate representation, such as XML document 102. The intermediate representation can be such that it can be used to produce server start scripts 104, 106, and 108 for multiple types of operating systems. The intermediate representation can be stored in memory.
The graphical user interface can allow the dragging and dropping of elements for the construction of the XML document. The graphical user interface can include selectable elements for the construction of the XML documents. The selectable elements can be selectable from a menu of the graphical user interface. The graphical user interface can allow the selection of the script for the correct operating system.
FIGS. 2A-2C show a graphical user interface (GUI) of one embodiment. As shown in FIG. 2A, a number of menus or palettes can be used for selecting a selectable element. For example, the menu 202 includes the selectable Control Structures, such as IF and FOR; Selectable Commands, such as PUSH, POP, COMMENT, ECHO, SHIFT, PIPE, EXIT, CALL (function), PAUSE, and XML marker; and selectable Parse Arguments such as parse arguments usage and parse arguments switch. Menu 204 allows a selection of an Environmental Variable, Execute Commands and Functions. Menu region 206 has the Script Elements tab selected. The script elements menu 206 indicates the script elements which can be used for producing the XML document from which the script or scripts can be produced. In this example, pull down menus are used for selecting elements within the script element structure. The script structure includes the parse arguments, which can parse the arguments passed to the script, the main script elements which include commands such as IF-THEN statements, echoes and function calls; and functional definitions. The functions can be called from within the main script portion.
FIG. 2B illustrates the XML representation menu for the GUI of FIG. 2A. This XML representation is in the menu area 208 with the XML tab selected. The XML script with its tags and other information can be automatically constructed by the GUI or other software from the user input to the script element server 206 of FIG. 2A. From the XML document, the script or scripts can be produced such as that that shown in FIG. 2C. When the script tab is selected, menu 210 displays with the produced script. The type of script to be produced or displayed be selected from a pull down menu, such as the pull down menu 212.
The construction of scripts from the XML can be automated by defining the XML tag structure (i.e., e.g., the document type definition DTD or XML schema) such that the XML document is sufficient to produce each type of script desired to be produced. In the script generator specification example given below, the XML document structure is such that both a WINDOWSTM command file script and a UNIX® shell script can be produced. The tags are used to identify information that can be plugged into the scripts automatically.
For example as shown below in the script generator specification example, XML for the IF-THEN statements can look as follows:












  <if>


    <test type=“error|string|file|directory|variable” not=“false|true”


case=“true|false -- WINDOWS ONLY”>


      <operand value=“op1” preserve=“true|false”/>


      <operand value=“op2” preserve=“true|false”/>


    <test/>


    <then>


      . . . execute command(s) when true . . .


    </then>


    <else>


      . . . execute command(s) when false . . .


    </else>


  </if>









The <if> and </if> tags indicate the whole if-then section. The <test> and </test> tags indicates the test to be done. The type is a variable to indicate the type of test. The <then> and </then> tags indicate the command or commands to execute if the test is true; and the <else> and </else> tags indicate the command or commands to execute if the test is true.
For example, if the type is string, not is false, and the case is false, script for checking if one string equals another string is given by:

if “string1”==“string2” command [else expression]

for a WINDOWSTM command file; and

if [“string1”=“string2”] then; else;

for a UNIX® shell script Where “string1” is obtained from “op1” and “string2” is obtained from “op2”.

The script generator specification example below is merely one non-limiting example of a specification of the script generator. A number of different representations for the XML can also be used as long as the desired types of constructed scripts can be produced.
