Jukka Zitting updated TIKA-116:
-------------------------------
Attachment: TIKA-116.patch
Attached a patch that implements streaming parsing for XML and OpenDocument
files.
The patch contains an implementation of a simple SAX-based XPath subset (in
o.a.t.sax.xpath) that is capable of processing all the XPath expressions in our
current codebase.

> The current OpenOfficeParser first reads the entire meta.xml and content.xml
> files from the given OpenDocument zip into memory, then parses the in-memory
> files to DOM trees, merges the trees, and finally evaluates a number of XPath
> expressions against the resulting DOM tree to extract metadata and document
> content. All this requires quite a bit of memory and multiple passes over the
> document.
> It would be better if the document could be streamed directly through zip and
> sax parsers without keeping a full copy of the document in memory or doing
> multiple passes over the document.
