Generic XML XPath helper with C# -


problem- have windows application loads xml file , other input takes xpath fetch data user wants given xml (obviously that's not problem). code snippet use load element given xpath like-

xpathdocument docnav; xpathnavigator nav; xpathnodeiterator nodeiter; xmlnamespacemanager manager;  docnav = new xpathdocument(filename); nav = docnav.createnavigator();  nav.movetofollowing(xpathnodetype.element); idictionary<string, string> names = nav.getnamespacesinscope(xmlnamespacescope.all);  manager = new xmlnamespacemanager(nav.nametable);  foreach (keyvaluepair<string, string> item in names) {     manager.addnamespace(item.key, item.value); }  nodeiter = nav.select(path, manager);

i have 1 sample xml below-

<fpml xmlns:ns="http://www.fpml.org/2005/fpml-4-2">   <header>     <messageid>ts4-xyz</messageid>     <sentby>xyz</sentby>     <creationtimestamp>2017-07-08t08:05:53.929z</creationtimestamp>   </header>   <trade>     <tradeheader>       <partytradeidentifier>         <partyreference href="our_party"/>         <tradeid tradeidscheme="uniqueid">aaaaaa</tradeid>       </partytradeidentifier>       <partytradeinformation>         <partyreference href="our_party"/>         <trader>dummy trader name</trader>       </partytradeinformation>       <tradedate>2017-07-08</tradedate>       <tsfpml:completeddatetime>2017-07-08t08:05:53.656z</tsfpml:completeddatetime>     </tradeheader>   </trade>   </fpml>

now, want retrieve 'trader' element value. works if use xpath query 

//*[local-name()="trader" , namespace-uri()='http://www.fpml.org/2005/fpml-4-2']

but fails load element if give /fpml/trade/tradeheader/partytradeinformation/trader

what change in xpath helper application required select nodes default namespace in general.

thank in advance!

you can remove namespaces using :

        public static string removeallnamespaces(string xmldocument)         {             xelement xmldocumentwithoutns = removeallnamespaces(xelement.parse(xmldocument));              return xmldocumentwithoutns.tostring();         }         private static xelement removeallnamespaces(xelement xmldocument)         {             if (!xmldocument.haselements)             {                 xelement xelement = new xelement(xmldocument.name.localname);                 xelement.value = xmldocument.value;                  foreach (xattribute attribute in xmldocument.attributes())                     xelement.add(attribute);                  return xelement;             }             return new xelement(xmldocument.name.localname, xmldocument.elements().select(el => removeallnamespaces(el)));         }

and called : 

var doc = new xmldocument(); doc.load(filename); doc.innertext = removeallnamespaces(doc.innertext); var nav = doc.createnavigator();
