XPATHS and Default Namespaces

What is the story behind XPATH and support for namespaces? Did XPATH as a specification precede namespaces? If I have a document where elements have been given a default namespace: <foo xmlns="uri" /> It appears as though some of the XPATH processor libraries won't recognize //foo because of the namespace whereas others w...

Can I create a value for a missing tag in XPath?

I have an application which extracts data from an XML file using XPath. If a node in that XML source file is missing I want to return the value "N/A" (much like the Oracle NVL function).

How to load an xml string in the code behind to databound UI controls that bind to the XPath of the XML?

Every sample that I have seen uses static XML in the xmldataprovider source, which is then used to databind UI controls using XPath binding. Idea is to edit a dynamic XML (structure known to the developer during coding), using the WPF UI. Has anyone found a way to load a dynamic xml string (for example load it from a file during runtim...

Getting The XML Data Inside Custom XPath function

Is there a way to get the current xml data when we make our own custom XPath function (see here). I know you have access to an XPathContext but is this enough?

Using SQL Server 2005's XQuery select all nodes with a specific attribute value, or with that attribute missing.

Update: giving a much more thorough example. The first two solutions offered were right along the lines of what I was trying to say not to do. I can't know location, it needs to be able to look at the whole document tree. So a solution along these lines, with /Books/ specified as the context will not work: SELECT x.query('.') FROM @x...

Choosing xpath version for .net IIS apps

We've got a .net CMS running on IIS 6 which uses xslt templates. It seems to be running xpath 1.0 (as we can't use any 2.0 functionality). How do we go about installing or specifying that IIS should use xpath 2.0? Is it installed per server, or can we specify which version to use on a per-application pool or per-site basis? Thanks a lo...
