How to change value of element with known path using XML

[=?Utf-8?B?VG9uZQ==?=]

Hi,

I need to change a value of an element in an XML file, I have been trying to
select the node to edit but can only get as far as component and have to
itterate through..

XmlDocument doc = new XmlDocument();
doc.Load("C:\\WINDOWS\\Panther\\Sysprep.xml");

// Create an XmlNamespaceManager to resolve the default namespace.
XmlNamespaceManager nsmgr = new
XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("bk", "urn:schemas-microsoft-com:unattend");

// Select and display all book titles.
XmlNodeList nodeList;
XmlElement root = doc.DocumentElement;
nodeList =
root.SelectNodes("/bk:unattend/bk:settings/bk:component", nsmgr);

Is it possible to select the computername element directly to edit or get to
the "settings pass="specialize" node?

nodeList =
root.SelectNodes("/bk:unattend/bk:settings/bk:component/bk:component

Post was probably a little unclear could someone tell me if its possible to
use selectnodes when node name have values, spaces etc..

this works --root.SelectNodes("/bk:unattend/bk:settings/bk:component"

this doesnt --root.SelectNodes("/bk:unattend/bk:settings/bk:component
name="Microsoft-Windows-Shell-Setup" processorArchitecture="x86"

Thanks..
