-----------------------------------------------------------------
Performance: kXml is about twice as fast as Xerces for both parsing to DOM and
serializing from DOM.
Memory Footprint:
xercesimpl 2.8.1 Impl: 1.2MB
kxml 2.2.2: 10KB
To be honest: using kxml instead of xerces requires the additional classes I
added in the second patch to JCR-1261 [1]. But these are small, and one has
even been copied ...
To me theses figures are quite impressive.

> Get rid of DOM for XML support
> ------------------------------
>
> Key: JCR-1312
> URL: https://issues.apache.org/jira/browse/JCR-1312
> Project: Jackrabbit
> Issue Type: Improvement
> Components: jackrabbit-webdav
> Reporter: Felix Meschberger
>
> Currently the web dav library uses Xerces and DOM to parse and create XML
> data. This mechanism is well-known but has two major issues: It is slow and
> it has a big memory footprint. In order to solve these two issues, I suggest
> to drop the use of the W3C DOM in webdav in favor of something easier and
> more straight forward to use.
> One candidate could be (out of my head and based on my bias towards KXml)
> KDOM. See also http://www.kxml.org.ww
> See also JCR-1261 for more discussions on this issue.
