Re^5: copyCurrentNode in XML::LibXML::Reader will add xmlns attribute ( setNamespaceDeclURI )

Anyone can explain why the namespace isn't changed?

Hi,

Its some kind of bug, if I were setup to compile libxml2 I'd narrow it down with this addition to LibXML.xs


int
_setNamespaceNULL(self )
        SV * self
    PREINIT:
        xmlNodePtr node = PmmSvNode(self);
    INIT:
        if ( node == NULL ) {
            croak( "lost node" );
        }
    CODE:
        xmlSetNs(node, NULL);
        RETVAL = 1;
    OUTPUT:
        RETVAL

My knowledge of C is less than basic (yes, I used Basic a lot as a child). But, I was able to compile the following and verify that libxml2 is able to clear the namespace, so the problem must lie in the XS land: #include <stdio.h> #include <libxml/tree.h> #include <libxml/parser.h> #include <libxml/xpath.h> #include <libxml/xpathInternals.h> int main (int argc, char *argv) { xmlInitParser(); xmlDoc document; document = xmlParseDoc("<r xmlns:p='http://p.p'><p:a>HERE</p:a></r>" +); xmlXPathContext xpc; xpc = xmlXPathNewContext(document); xmlXPathRegisterNs(xpc, "p", "http://p.p"); xmlXPathObject xp; xp = xmlXPathEvalExpression("/r/p:a", xpc); if (xp == NULL) return(1); xmlNodeSet nodes; nodes = xp->nodesetval; xmlNode node; node = nodes->nodeTab[0]; xmlSetNs(node, NULL); xmlChar s; int size; xmlDocDumpMemory(document, &s, &size); char string; string = (char )s; printf("%s", string); return(0); } [download] Outputs: `<?xml version="1.0"?> <r xmlns:p="http://p.p"><a>HERE</a></r>` [download] ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7*2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l] [select]

Should work now. ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l]
