Please forgive me, this is *surely* a FAQ, but several hours of poring over
libxml2 documentation has left me high and dry.
My question is this: I have a document and a DTD spec. I want to parse the file
& validate against the DTD in such a way that the whitespace ruled out by the
DTD is either removed or detectable.
Let me be more concrete.
Here's a totally-ordinary xml file with a self-contained DTD:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE people_list [
<!ELEMENT people_list (person)*>
<!ELEMENT person (name , birthdate? , gender? , socialsecuritynumber?)>
<!ELEMENT name (#PCDATA)>
<!ELEMENT birthdate (#PCDATA)>
<!ELEMENT gender (#PCDATA)>
<!ELEMENT socialsecuritynumber (#PCDATA)>
]>
<people_list>
<person>
<name>Fred Bloggs</name>
<birthdate>27/11/2008</birthdate>
<gender>Male</gender>
</person>
</people_list>
Using xmlParseFile, I can read and validate it just fine. The parsed document's
'properties' of 11 indicates (among other things) that DTD validation was
successful. However, even with the inline dtd spec, the people_list element
(for instance) is observed to have three children: the whitespace, the person,
and the whitespace. I had a flash of hope when I discovered the
'xmlIsBlankNode' function... sadly, it appears that this function returns zero
even on the whitespace-only nodes.
I'm certainly hoping that this is a simple question. I've been through the FAQ
and the example code quite a number of times.
Many thanks in advance for any help whatsoever; an RTFM (with a pointer) would
be just fine with me.
Your obedient servant, &c.
