XPath

[Techno]

trying to extract all the child nodes where the rootnode is called "Abc"

xml:

<role>
<name>"ABC"</name>
<values id=1>
<value>123</value>
<stuff>asdasdasd</stuff>
</values>
<values id=2>
<value>123</value>
<stuff>asdfdffsdfsdasdasd</stuff>
</values>
</role>


how can I use XPath to return me all nodes from a root node called "ABC"?

Assuming role is under the root node and the nodes you want to select...


"/role[name=ABC]"

Haven't tested it, but that's my guess..

Just need some quotes around ABC.

//role[name='ABC']

hmm. still need to get a hang of this. Actually i mis typed the xml doc. should be:

<someRootNode>
<role>
<name>"ABC"</name>
<values id=1>
<value>123</value>
<stuff>asdasdasd</stuff>
</values>
<values id=2>
<value>123</value>
<stuff>asdfdffsdfsdasdasd</stuff>
</values>
</role>

</someRootNode>

That's what we were assuming. The above should work for that.

XmlDocument xd = new XmlDocument();
xd.Load(@"c:\test\test.xml");
 
XmlNode nod = xd.SelectSingleNode("//role[name='ABC']");
if (nod != null)
{
    MessageBox.Show(nod.InnerXml);
}

what about selecting ALL nodes where the node name is "ABC" - i want to select all nodes in that node

so..

<someRootNode>

<role>
<name>"ABC"</name>
<values id=1>
<value>123</value>
<stuff>asdasdasd</stuff>
</values>
<values id=2>
<value>123</value>
<stuff>asdfdffsdfsdasdasd</stuff>
</values>
</role>

</someRootNode>


should get me the values for valueid1 and valueid2 and valueidX etc...

[nemaroller]

So you want to select all <value> nodes where the outtermost containing <role> node contains a <name> node whose value is 'ABC'?

[nemaroller]

XmlNodeList nodelist = xd.DocumentElement.SelectNodes("//role/values[value=123]");

[nmadd]

If you want to check for the ABC name first you can try something like this:
//role[name='ABC']/values
