Transformer documentation: se_tpb_syncpointNormalizer
Transformer Purpose
This transformer performs synchronization point normalization on a XML document. It is used as a step
in the Narrator transformer chain, making sure each synchronization point in a DTBook file is contained in its own
XML element. For example, the transformer inserts <span> elements around the text nodes before
and after an inline <pagenum> element.
Input Requirements
The transformer has only been tested with DTBook documents created while running the Narrator
transfomer chain. While the transformer is able to detect the document type and use different configuration files,
there is only support for DTBook documents having sentence level markup.
Output
On success
A document where each synchronization point is a separate XML element, making it possible to represent each
synchronization point as a fragment i SMIL.
On error
On error, this transformer will throw an exception and abort execution.
Configuration/Customization
Parameters (tdf)
- input
- The input XML document.
- output
- The output XML document.
Further development
- Support for compound XML documents.
- Support for different synchronization levels (word, sentence, paragraph, level).
Dependencies
The transformer uses StAX for XML processing.
