#273 LVXMLParser ignores CDATA data

[luran]

I have several epub files contain CDATA data in toc.ncx, something like this:
<navPoint id="chapter3" playOrder="3">
<navLabel><text><![CDATA[Chapter 1]]></text></navLabel>
<content src="Text/Chapter_1.html"/>
</navPoint>
When crengine parse this file, it seems to treat the whole CDATA chunk as another tag, so the value of the text label becomes empty, and the TOC entry is ignored.
