Hi All, I'm having two issues when using libxml and its with my code only. But please let me know, how to get this fixed.
1. A problem with the memory issue, I guess. With the below piece of code, in the constructor I have already created a xpathCtx = xmlXPathNewContext(tree); And then, I have written a xpatheval method, which gets the path to be evaluated. Because I evaluate the xpath expression in many places, I have written this method. But with this, sometimes there is a segmentation fault in the xmlXPathEvalExpression( ) call. (when executing 10 times, twice it gives segv). How can I debug the memory issues with the libxml api's call or what could be wrong here? xmlNodeSetPtr OTAccess::OTxmlXPathEvalExpression(string path) { const xmlChar* cpath = xmlCharStrdup(path.c_str()); xpathObj = xmlXPathEvalExpression(cpath, xpathCtx); xmlFree((void*)cpath); return (xpathObj->nodesetval); } 2. Another problem is, I wrote a test program which sets the content of an element using xmlNodeSetContent(pnode, "100.100.100.100"), which is working fine. But when I used it in my actual code, xmlNodeSetContent(pnode, " 100.100.100.100"), it gives the following error. Access.cpp:100: error: invalid conversion from 'const char*' to 'const xmlChar*' Access.cpp:100: error: initializing argument 2 of 'void xmlNodeSetContent(xmlNode*, const xmlChar*)' Should I need to type cast to const xmlChar*. Even then, how it worked in the test program. Please help me to fix these problems. Thanks Senthil
