Abstract: A system and method for dynamically generating Web content using a parse tree is described. A template describing a dynamically generated Web page is built. The template includes a script written in a tag-delimited page description language. One or more markers included within the template each indicate a relative location within the Web page for dynamic content insertion. The hierarchical nature of the page description language is used to infer a set of display regions, which are referenced by a parse tree. The parse tree includes a plurality of nodes structured into levels. Each node corresponds to structural tags specified within the script. Each successive level represents a further nesting of the structural tags within the script. A controller program invokes a document engine and specifies a particular template. Each marker may be substituted with dynamic content zero, one or several times each.
