c# - Node is not removed from XmlDocument -


edit: found bug. xmlnodelist nodes = mydoc.selectnodes("//dict/dict/dict"); has wrong structure. correct xml schema "/plist/dict/dict/dict" , correct output. removing nodes still not work though end edit

in code, seems fine except nodes want delete not deleted.

xmldocument mydoc = new xmldocument();     mydoc.load(@"c:\users\boston\documents\visual studio 2010\websites\itunes\itunes music library.xml");     xmlnodelist nodes = mydoc.selectnodes("//dict/dict/dict");      response.write(nodes.count + " nodes found in xml file <hr>");      string s1;      (int = 1; <= nodes.count -1; i++)     {         foreach (xmlelement s in nodes[i])         {             s1 = s.innertext;             int j = s1.compareto("location");             if (j == 0)             {                 s1 = s.nextsibling.innertext;                 if (s1.contains("201.mp3"))                 {                     response.write(s1.tostring() + "<br>");                     nodes[i].parentnode.removechild(nodes[i]);                  }             }         }          }      mydoc.save(@"c:\users\boston\documents\output4.xml");

the culprit line might this. doing wrong ?

nodes[i].parentnode.removechild(nodes[i]);

a similar post how remove xmlnode xmlnodelist exist , applied syntax not work.

edit:

looks problem in line xmlnodelist nodes = mydoc.selectnodes("//dict/dict/dict");

if use //dict//dict path, same result. same case //dict path. if use "/dict/dict/" 0 results in screen print outs.

i copy piece of xml file may through light on problem.

first of trying remove node in for/foreach loop. cannot this.

           (int = 1; <= nodes.count -1; i++)            {                foreach (xmlelement s in nodes[i])                {                   nodes[i].parentnode.removechild(nodes[i]); //cannot remove element nodes[i].                }            }

instead can

       var list = new list<xmlelement>();        (int = 1; <= nodes.count -1; i++)        {            foreach (xmlelement s in nodes[i])            {              list.add(nodes[i]);            }        }        foreach(var listtemp in list)        {           nodes.remove...(listtemp);        }

you need put element in temporary list , remove outside loop.
