Selecting Nodes using doc.selectnode()

[libish]

hi all,
i have an xml document. it contains several nodes...
here i want to select a particular node containing the name say "$abc"
so i'm using this

docXML3.SelectN odes("$abc=*abc *123");

but here an exception is raised telling that the expression ("$abc=*abc *123" )not supported.
what should i do to avoid this situation?

thanks in advance.

yes it is in c#.Net.

here what i'm doing is.. i got an xml file containing parameters for my application
the parameter names are represented by "$parametername "
here in my xml file the parameter will be like

<var>
<v>"$para=12343 "</v>
<v>"$para2=*hag r"</v>
</var>

at some point in my project i wll be in need to change the parameter value for
"$para"

this is how this situation arised...
here i need to modify the node with new values...
for that what should i do?

Try something like this

XmlDocument.xmlDetails = new XmlDocument();
xmlDetails.Load(@"MyDir\Templates\Setup.xml");
XmlNodeList nodeList = xmlDetails.GetElementsByTagName("Settings");

                foreach (XmlElement elem in nodeList)
                {
                    foreach (XmlElement tempElem in elem.ChildNodes)
                    {
                        if (tempElem.Name == "Setup")
                        {
                            myString Variable = tempElem.InnerText;
                        }
                        if (tempElem.Name == "Value")
                        {
                            tempElem.InnerText = "A string value";
                        }
                     }
                  }

xmlDetails.save(@"MyDir\Templates\Setup.xml");
