Patent ID: 7461337

Claim:
A computer-implemented method for excluding structures from a markup document comprising the steps of: identifying a section within a first markup document into which at least a portion of a second markup document is to be inserted; combining a plurality of exception markup documents into a portal exception markup document specifying restricted structures associated with said section of said first markup document and specifying handling instructions for actions performed if at least one restricted structure is detected within said portion of said second markup document, wherein each restricted structure defines a non-allowable format or data type not allowed by said section of said first markup document, wherein said first markup document, said second markup document, and said exception markup document are specified in a same markup language, wherein said plurality of combined exception markup documents are selected from documents specifying browser-related restricted structures, documents specifying hardware restricted structures, documents specifying portal-defined restricted structures, documents specifying content provider restricted structures, and documents specifying user-defined restricted structures, wherein the portal exception markup document is not restricted to a particular markup language; comparing said portion of said second markup document with the restricted structures associated with said section of said first markup document specified within said portal exception markup document; if no restricted structure is found by said comparing step, inserting said portion of said second markup document into said section of said first markup document; and, if at least one restricted structure is found by said comparing step, performing at least one action based on said handling instructions, said at least one action comprising displaying a message indicating that restricted structures exist within said portion of said second markup document and presenting one or more user selectable handling choices for said restricted structure.
