c# - Parsing a element with name space not working xpath -
i no got shot downwards before inquire tried implmenting name space xml still not working xml document service center maanger.
public void getcriteraparamters(string queryparmeterstring, string xpath) { list<querycritera> listcriteraparameter = new list<querycritera>(); xmldocument currentdocument = new xmldocument(); currentdocument.loadxml(queryparmeterstring); string path = xpath; xmlnodelist nodelist = currentdocument.selectnodes(path); xmlelement elm = currentdocument.documentelement; xmlnodelist listcritera= elm.childnodes; xmlnamespacemanager nsmgr = new xmlnamespacemanager(currentdocument.nametable); nsmgr.addnamespace("querycriteria", "http://microsoft.enterprisemanagement.core.criteria/"); var topicnodes = currentdocument.selectnodes("expression", nsmgr); list<querycritera> qp = new list<querycritera>(); string itemsource=""; (int = 0; < listcritera.count; i++) { querycritera qplist = new querycritera(); string mystring = listcritera[i].innerxml.tostring(); string xml2 = xelement.parse(mystring).tostring(); xmldocument currentdocument2 = new xmldocument(); currentdocument2.loadxml(xml2); xmlnodelist nodelist2 = currentdocument.selectnodes(xpath); foreach (xmlnode node in nodelist2) { itemsource = node.innerxml; } } } i need able select nodes under cirtiera look ones.

when using xmldocument xml has namespaces in it, need utilize xmlnamespacemanager create aliases namespaces. in xpath statements utilize aliases in front end of element names. give try:
xmldocument doc = new xmldocument(); doc.load("xmlfile1.xml"); // give namespace alias utilize in our xpath statement xmlnamespacemanager mgr = new xmlnamespacemanager(doc.nametable); mgr.addnamespace("a", "http://microsoft.enterprisemanagement.core.criteria/"); // find criteria node tagged "a" namespace xmlnode node = doc.selectsinglenode("//a:criteria", mgr); console.writeline(node.outerxml); c# xml parsing
