[xml] escaping in xpath

[Fazekas Andrea <fazek ludens elte hu>]

Hi All!

I have a document which contains:

...
<entry name="def[ name='config']"/>
...

and i would like to evaluate an xpath expression which contains:

.../entry[ name="def[ name='config']"]/...

is there a way to escape ;, ", @, [, etc in libxml2?

Thanks,
        Andrea
