I tried your xml file and XPath query using the example program 'xpath1' included in libxml2 distribution, and got the following results (note that the following command should all be on a single line): [EMAIL PROTECTED] work]$ ./xpath1 bug.xml '/roap:riHello/extensions/[EMAIL PROTECTED]:type="roap:CertificateCaching"]' "xsi=http://www.w3.org/2001/XMLSchema-instance roap=urn:oma:bac:dldrm:roap-1.0" Result (1 nodes): = element node "extension" [EMAIL PROTECTED] work]$ Perhaps you could analyze what is the difference between your code, and the way in which this example program behaves (which appears to be correct)? > The code: > xpathCtx = xmlXPathNewContext(doc); > xmlXPathRegisterNs(xpathCtx, (xmlChar *)"roap", (xmlChar > *)"urn:oma:bac:dldrm:roap-1.0"); > xmlXPathRegisterNs(xpathCtx, (xmlChar *)"xsi", (xmlChar > *)"http://www.w3.org/2001/XMLSchema-instance";); > > xpathObj = > xmlXPathEvalExpression("/roap:riHello/extensions/[EMAIL > PROTECTED]:type=\"roap:CertificateCaching\"]", > xpathCtx); > > if (xpathObj->nodesetval->nodeNr > 0) > > XML: > <?xml version="1.0" encoding="utf-8"?> > <roap:riHello xmlns:roap="urn:oma:bac:dldrm:roap-1.0" > xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; status="Success" > sessionId="433211"> > <selectedVersion>1.0</selectedVersion> > <riID> > <keyIdentifier xsi:type="roap:X509SPKIHash"> > <hash>aXENc+Um/9/NvmYKiHDLaErK0gk</hash> > </keyIdentifier> > </riID> > <riNonce>dsaiuiure9sdwerfqwer</riNonce> > <trustedAuthorities> > <keyIdentifier xsi:type="roap:X509SPKIHash"> > <hash>aXENc+Um/9/NvmYKiHDLaErK0gk</hash> > </keyIdentifier> > <keyIdentifier xsi:type="roap:X509SPKIHash"> > <hash>aXENc+Um/9/NvmYKiHDLaErK0gk</hash> > </keyIdentifier> > </trustedAuthorities> > <extensions> > <extension xsi:type="roap:CertificateCaching" /> > </extensions> > </roap:riHello> Bill _______________________________________________ xml mailing list, project page http://xmlsoft.org/ [email protected] http://mail.gnome.org/mailman/listinfo/xml
