How does XPP support XML?
- Enables transformation of content on import or export using XSL stylesheets and an XSLT engine.
- XML structure and attributes can be used to control formatting characteristics. XPath context can be used to map diverse or unique formatting instructions to tags of the same name.
- Supports the manipulation of structure through the interactive XyView, letting the user:
- Navigate the page by structure.
- Request a validating parse after edits.
- Follow errors to their source in the document.
- Control display of tags and processing instructions in the Line Editor.
- Supports CALS table and MathML mark-up.
- Supports Perl and its XML libraries for manipulating content during composition.
