2 XSLT Modules

2.1.1 Named template: xtlc:compare-documents as element(xtlc:message)*

Compares two XML documents with each other:

• Comments and processing instructions are ignored

• Text nodes are normalized before comparison

• Empty text nodes (after normalization) are ignored

• The comparison stops after the first difference is encountered.

• The result is either:

  • An empty set, when no differences found

  • One or more xtlc:message elements, status="error" when differences were found (you can only get more than one message on attribute differences)
