XML Functions

Use DAL XML API functions to let Documaker applications access specified XML documents and retrieve XML data via a DAL script. These functions are registered in keywords, called built-in functions. An XML built-in function performs an operation on a set of parameters and returns a DAL variable in one of the three types: list, integer, or string.

The XML functions are summarized in the table below. Click the function name to jump to a discussion of that function.
