Linq To Xml - Unexpected search results
Just when I was thinking that I had Linq To Xml sussed I'm faced with yet another开发者_StackOverflow中文版 error! I think if I was to understand the linq search process in general better I might have more success, so any good links regarding that are also welcome. To my problem however; using the code below:
Dim xd As XDocument = _
<?xml version="1.0" encoding="utf-8"?>
<root>
<element>
<subelement id="1"/>
<subelement id="2"/>
<subelement id="3"/>
</element>
<element>
<subelement id="4"/>
<subelement id="1"/>
<subelement id="5"/>
</element>
</root>
Dim results = _
From q In xd.Descendants.<element> _
Where q.<subelement>.@id = 1
For Each xe As XElement In results
Console.WriteLine(xe.ToString)
Next
I would have expected the above code to return both 'element' nodes, but it only returns the first because it only searches the first 'subelement' node within 'element', how can I make the where clause apply to all 'subelement' nodes?
You could do
Dim results = _
From q In xd.Descendants.<element> _
From p In q.<subelement> _
Where p.@id = 1
(That is, if my VB.NET is up to the task here... I could do it in C#. Please feel free to edit.)
