Linq to XML - Namespaces
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Book List</title>
</head>
<body>
<blist:books
xmlns:blist="http://www.wrox.com/books/xml">
<blist:book>
<blist:title>XSLT Programmers Reference</blist:title>
<blist:author>Michael Kay</blist:author>
</blist:book>
</blist:books>
</body>
</html>
from the given Xml document,I want to iterate all <blist:books> elements.
(i.e) How to i handle the namespace ?
i tried
XNamespace blist = XNamespace.Get("http://www.wrox.com/books/xml");
XElement element = XElement.Load("Books.xml");
IEnumerable开发者_开发百科<XElement> titleElement =
from el in element.Elements(blist + "books") select el;
but the enumeration (titleElement) does not return any result.
You have two different problems here.
- You're calling the
Elementsmethod, which returns the direct child elements of the element you call it on. Since the<html>element has no direct<blist:books>child elements, you aren't getting any results. - XML is case sensitive. You need to write
books, notBooks.
Also, there's no point in writing from el in whatever select el. Unless you put addition logic (such as a where or orderby clause, or a non-trivial select), you should just write whatever.
Therefore, you need to replace your LINQ query with the following:
IEnumerable<XElement> titleElement = element.Descendants(blist + "books");
