c# - XPath select node in Xaml -

i match node within xaml-file , file looks this:

some xaml (xml-like) input:

<somenode> <!-- root btw -->     <!-- [...] -->     <somenode.anyproperty>         <!-- [...] -->     </somenode.anyproperty>     <!-- [...] --> </somenode> 

and want math section 'somenode.anyproperty'. afterwards want replace found node generated one.

any suggestions working xpath expression? tried common expression apply on usual xml-file like: "somenode.anyproperty". sure, did not worked.

working solution:

thanks support. problem not xpath expression itselft. furthermore namespace declaration of xaml input file. avoid namespace problems used modified version of @malkam solution.

  xdocument doc = xdocument.load("somefile.xaml");   //get required element   xelement nodetoreplace = doc.elements().where(x => x.name.localname == "somenode.anyproperty").firstordefault() xelement;   //replace requried element   nodetoreplace.replacewith(someothernodeigeneratedearlier);   doc.save("somefile_editet.xaml"); 

try this.

//load xml in xelement string xml="xml"; xelement xmltree=xelement.parse(xml); //get required element xelement child = xmltree.element("somenode.anyproperty"); //replace requried element child.replacewith(     new xelement("newchild", "new content") );
