My Input
<A xmlns="http://abc.com">
<B>"b"</B>
<C>"c"</C>
</A>
My Code
XNamespace ns = XNamespace.Get("http://abc.com");
var query= from node in doc.Descendants(ns+ "A")
select new
(
B = (string)node.Element(ns+"B"),
C = (string)node.Element(ns+ "C")
);
My Question
Do I have to add ns
every time I am doing node.Element()
? or is there any other way?
The most important advantage of LINQ to XML is its integration with Language-Integrated Query (LINQ). This integration enables you to write queries on the in-memory XML document to retrieve collections of elements and attributes.
Do I have to add ns every time I am doing node.Element()?
Yes, basically. You're looking for (say) an element with a local name of B
and a namespace URI of "http://abc.com".
You could write your own extension method which matched any element with the right local name, but I'd advise against it. It would be something like:
public IEnumerable<XElement> ElementsWithLocalName(this XContainer container,
string localName)
{
return container.Elements().Where(x => x.Name.LocalName == localName);
}
public IEnumerable<XElement> ElementsWithLocalName<T>(
this IEnumerable<T> source,
string localName) where T : XContainer
{
return source.Elements().Where(x => x.Name.LocalName == localName);
}
This would make your code less reliable though - do you really want to match just any old name with the right local name?
