For example, if the name table of an XmlReader object is used, after each read, any namespace and prefix strings pushed into the name table can be re-used by XmlNamespaceManager. For more information on atomized strings, see XmlNameTable. If you specify an existing name table, any namespaces in the name table are not automatically added to XmlNamespaceManager. You must use AddNamespace and RemoveNamespace to add or remove namespaces.

It almost seems like you are the only person trying to do this It didn't make sense - Why should you have to hardcode the namespace you expect when its in the header? SelectSingleNode "descendant::my:item", namespaceManager ; namespaceManager. PushScope ; namespaceManager. PopScope ; Another option is to parse the attributes in the header and look for any contained namespaces foreach XmlAttribute attribute in doc.

I don't think you have control over the names of elements and namespaces in InfoPath forms - they are autogenerated — Vroomfundel.

Resolves, adds, and removes namespaces to a collection and provides scope management for these namespaces. XmlNamespaceManager stores prefixes and namespaces as strings.

Here's a summary of management and lookup tasks you can perform with this class. For more information and examples, follow the links to the reference page for each method or property. To add namespaces to the namespace manager, you create a XmlNamespaceManager object and then use the AddNamespace method.

Default prefix and namespace pairs are automatically added to the namespace manager on creation. When you create the namespace manager, you can specify a name table from the XmlReader , XsltContext , or XmlDocument class, and then use the AddNamespace method to add the namespaces.

You can supply the XmlNamespaceManager object as a parameter to the SelectNodes or SelectSingleNode method of the XmlDocument class to execute XPath query expressions that reference namespace-qualified element and attribute names. The namespace manager assumes that prefixes and namespaces have already been verified and conform to the W3C Namespaces specification.

The namespace manager does not perform any validation. The namespace manager atomizes the strings when they are added by using the AddNamespace method and when a lookup is performed by using the LookupNamespace or LookupPrefix method.

But it looks like. So, does anyone know why you ever need to add a default namespace to an XmlNamespaceManager instance? For XPath 1. But there are possible uses of XmlNamespaceManager where you might be interested whether a default namespace is defined and then you can use that property. And if. NET some day gets an XPath 2.
