Is this a principle limitation of the xmlParseDoc API or only an
accidental API lack? Which API is suitable to read cdata? Sorry for my
stumbling asking, I am new to libxml and xml.

I probably miss the point. Do you mean I should use the command line
tool 'xmllint'? This would be rather inconvinient for me. I have ready (more
or less) a C program - using the xmlParseDoc API - which reads an XML file,
where the cdata content is only a small piece of. As a workaround to get
the cdata I evaluate currently the three strings
"___...___"
"...___"
"___"
(in the said symbolic meaning) which I get when I parse through the
children of the <data> element using xmlNodeListGetString(). Is that
something I should not rely on?
Thanks for your response
Hartmut
