Hi there,
As mentioned in an earlier thread, I ran into some weird behavior concerning Relax NG include processing. It may be that I'm misunderstanding something, but I thought I'd run it by the list.
Take the following program:
#include <stdio.h> #include "libxml/parser.h" #include "libxml/relaxng.h"
int main() {
xmlDocPtr doc;
xmlParserCtxtPtr pctxt;
xmlRelaxNGParserCtxtPtr rng_pctxt;
xmlRelaxNGPtr schema;xmlInitParser(); pctxt = xmlNewParserCtxt(); doc = xmlCtxtReadFile(pctxt, "test1.rng", NULL, 0); rng_pctxt = xmlRelaxNGNewDocParserCtxt(doc); schema = xmlRelaxNGParse(rng_pctxt); }
Place it in a directory which contains the following rng files:
test1.rng
<grammar ns="http://www.w3.org/1999/xhtml"; xmlns="http://relaxng.org/ns/structure/1.0";>
<include href="test2.rng"/>
</grammar>
test2.rng
<grammar xmlns="http://relaxng.org/ns/structure/1.0";>
<start> <ref name="a" /> </start>
<define name="a"> <element name="a"> <text/> </element> </define>
</grammar>
Now if you compile and run the program, it should work -- the test1.rng should load successfully, loading test2.rng in turn.
Now create a subdirectory called 'sub', and place test1.rng and test2.rng in there.
Now change the program so it loads sub/test1.rng instead of test1.rng.
when I run this I get the following error:
I/O warning : failed to load external entity "test2.rng"
element include: Relax-NG parser error : xmlRelaxNG: could not load test2.rng
element include: Relax-NG parser error : Failed to load include test2.rng
Relax-NG parser error : grammar has no children
Relax-NG parser error : Element <grammar> has no <start>
This is against libxml2-2.6.16 on a linux box.
So, am I doing something wrong, or is this a bug? Things do appear to work as expected if I use xmlRelaxNGNewParserCtxt() and give it the "sub/test1.rng" path instead.
