Finding a node in xml file with libxml2

c, libxml2, xml-parsing

Solution

Your function is correct. Add a debugging line to see why it doesn't work in your case. For example:

    printf("xmlStrcmp(%s, %s)==%d\n", node->name, nodename,
        xmlStrcmp(node->name, nodename));

But you don't really need that function. You may use xmlXPathEval.

Problem

I am trying to write a function that will find a node with a specified name in a xml file. The problem is that the function never finds the specified node. ``` xmlNodePtr findNodeByName(xmlNodePtr rootnode, const xmlChar * nodename) { xmlNodePtr node = rootnode; if(node == NULL){ log_err("Document is empty!"); return NULL; } while(node != NULL){ if(!xmlStrcmp(node->name, nodename)){ return node; } else if(node->children != NULL){ node = node->children; xmlNodePtr intNode = findNodeByName(node, nodename); if(intNode != NULL){ return intNode; } } node = node->next; } return NULL; } ``` I can see in the debugger that function does go deep into the sub nodes but still returns NULL. Thanks in advance.
