<?xml version="1.0" encoding="utf-8"?> <reminders>   <reminder>     <title>alarm1</title>     <description>desc1</description>     <time>03/07/2012 10:11am</time>     <snooze>1</snooze>     <repeat>none</repeat>   </reminder> </reminders> 

and want modify innertext alarm1 value wrote code duplicate entire node .

        xmldocument xml = new xmldocument();          xml.load("0.xml");          xmlnodelist elements = xml.selectnodes("//reminders");          foreach (xmlnode element in elements)         {             if (element.innertext == "alarm1")             {                 xmlnode newvalue = xml.createelement("modified");                 element.replacechild(newvalue, element);                  xml.save("0.xml");             }         } 

and tried code :

        foreach (xmlelement element in xml.selectnodes("//reminder"))         {             if (element.innertext == "alarm1")             {                 xmlnode newvalue = xml.createelement("modified");                 element.replacechild(newvalue, element);                  xml.save("0.xml");             }         } 

but doesn`t work....

edit 1 : [figured out new code]

        xmldocument xml = new xmldocument();          xml.load("0.xml");          foreach (xmlelement element in xml.selectnodes("//reminder"))         {             foreach (xmlelement element1 in element)             {                 if (element.selectsinglenode("//title").innertext == "alarm1")                 {                     xmlnode newvalue = xml.createelement("modified");                     element.replacechild(newvalue, element1);                      xml.save("0.xml");                 }             }         } 

but made alarm1 becomes

<modified /> 

edit 2 : [i solved :d] okay here code figure out :

        xmldocument xml = new xmldocument();          xml.load("0.xml");          foreach (xmlelement element in xml.selectnodes("//reminder"))         {             foreach (xmlelement element1 in element)             {                 if (element.selectsinglenode("//title").innertext == "alarm1")                 {                     messagebox.show(element1.innertext);                     xmlnode newvalue = xml.createelement("title");                     newvalue.innertext = "modified";                     element.replacechild(newvalue, element1);                      xml.save("0.xml");                 }             }         } 

i`ll appreciate helps , thanks.

try this:

xml.selectsinglenode("//reminder/title").innertext = "newvalue"; 

your foreach line looping through list of elements called "reminders", not it's child nodes.
