Googleing on the topic I've just found this hint:

Mozilla's XML parser is known to create a single text node for each
chunk of 4096 characters so there you will certainly encounter the
problem. The data is not lost however, you will simply end up with an
element in the DOM that has several text child nodes.
Workarounds are using e.g.
instead of accessing firstChild and its nodeValue or to force
normalization of the XML document by calling
first, then you can access firstChild.nodeValue as adjacent text nodes
have been merged into one node.
Note that the textContent property is part of W3C DOM Level 3 and only
newer Mozilla versions support that property.

I will try, but not immediatly. The idea is to change the line:
text = domElement.firstChild.data;
in method kaXmlFeature.prototype.parseElement
