Ah, thanks for the pointer. It looks like for the DOCUMENT case,
we could maybe relax this restriction by passing the XML_PARSE_HUGE
option to xmlCtxtReadDoc(). However, there are things to worry about:
Just a remark from the sidelines, from someone having done a fair bit of XML in years past.
That XPath is simple, and a streaming parser (SAX or StAX) could handle it. While that
XML_PARSE_HUGE option probably applies to a DOM parser. So is there a work-around
to somehow force using a streaming parser instead of one that must produce the whole Document,
just so a few elements are picked out of it? FWIW. --DD
