Null returned when selecting a node in XML document

问题 New to XML. I have a 3rd party webservice that supplies an XML document that I have to update the element values and pass back. The core issue issue is I get an NullReferenceException error when calling the node.RemoveAll() method in the code below. I'm calling the RemoveAll() method because each element has the xsi:nil attribute when it is supplied to me, and if I don't remove it before updating the element value, the XML won't validate by the webservice. The XML document supplied by the 3rd

Using XPath in SelectSingleNode: Retrieving individual element from XML if it's present

由 爷，独闯天下 提交于 2019-12-21 03:41:42
问题 My XML looks like : <?xml version=\"1.0\"?> <itemSet> <Item>one</Item> <Item>two</Item> <Item>three</Item> .....maybe more Items here. </itemSet> Some of the individual Item may or may not be present. Say I want to retrieve the element <Item> two </Item> if it's present. I've tried the following XPaths (in C#). XMLNode node = myXMLdoc.SelectSingleNode("/itemSet[Item='two']") --- If Item two is present, then it returns me only the first element one . Maybe this query just points to the first

Why is XmlNamespaceManager necessary?

问题 I've come up kinda dry as to why -- at least in the .Net Framework -- it is necessary to use an XmlNamespaceManager in order to handle namespaces (or the rather clunky and verbose [local-name()=... XPath predicate/function/whatever) when performing XPath queries. I do understand why namespaces are necessary or at least beneficial, but why is it so complex? In order to query a simple XML Document (no namespaces)... <?xml version="1.0" encoding="ISO-8859-1"?> <rootNode> <nodeName>Some Text Here
