"filtering" an XML file

[Felicity]

Hello,

I have the following basic XML file:

<ProductX>
<Settings>
<FormA>
<TextBox1>
<value>ABC</value>
</TextBox1>
<TextBox2>
<value>XYZ</value>
</TextBox2>
<FormA>
<FormB>
<TextBox1>
<value>123</value>
</TextBox1>
</FormB>
</Settings>
</ProductX>

I want to be able to "filter" the XML on the load of a
form so that I only have the Nodes with the FormA tags. I
cannot work out how to do this. Any help would be
appreciated.

Thanks in advance,

Felciity

XmlDocument doc = new XmlDocument();
doc.Load("yourxmldoc.xml");

XmlNodes xNodes = doc.SelectNodes
("//ProductX//Settings//FormA");

That should do it.

It can be done in many ways: XSLT, customized XmlTextReader, XPath selection
over XmlDocument or XPathDocument etc. Which one do you prefer?

Hello,

I am interested in finding out about the XPath method. But, I may be
interested in finding out about other methods also. Can you give me
some indication of a resource that has some decent code samples and
explanations about these methods?

Thanks in advance,

Felicity

XPath approach is to load your XML document into XPath navigable object
(XmlDocument, XPathDocument, XmlDataDocument), and then query appropriate
portion of data:
XmlDocument doc = new XmlDocument();
doc.Load("foo.xml");
XmlNode formA = doc.SelectSingleNode("/ProductX/Settings/FormA");
But, I may be

MSDN is the best resource. Read about XmlReader - you can create customized
filtering XmlReader, that's going to be the most effective, but not simplest
solution.
