XPath to navigate through elements and attributes in an XML document
returned  by a SharePoint Web Service. 
This article proposes some
examples which will show to developers how to use XPath in spite of namespaces
present in the XML returned by Web services of SharePoint

provides Web Services that can be consumed in order for example to get data
from a SharePoint Site, and display them within another web site or a
desktop application.
It is a part of what is commonly called "SOA" in
companies.
On the other hand, this principle can be applied to retrieve data
from SharePoint Internet facing web site so as they can be a part of a mashup in
a web site.

allows developers to quickly navigate through elements and attributes in an XML
document. It is very useful when there is no namespaces in the parsed XML, but
it becomes more difficult when namespaces are used in the XML, especially if
there is several namespaces and that they are present at different locations
within the XML code.

The Lists Web service provides methods for working with
SharePoint lists, content types, list items, and files.

The GetListCollection Method returns the names and GUIDs for all lists in a

this is the first example that shows how to manage the namespaces concern with
