If the optional prefixes are used to specify the namespaces of the node in the XPath query, the prefixes must be specified as one or more string arguments after the XPath (see the second example). Xml中SelectSingleNode方法，xpath查找某节点用法 Element, 指形如
My apologies if I missed a step. If you need more reference, the classes work very similar to how they work in C#. Reply. That's bizarre! They removed selectSingleNode but didn'r add support for document.evaluate.

You need to change the SelectSingleNode call to use this namespace.
This XML tool evaluates the XPath expression and changes the node value of the first node that satisfies the pattern. This is
XML SelectSingleNode isn't returning a value. I am at a loss on this. I have tried many different examples I have by googling but I'm still having
In order to find nodes in an XML file you can use XPath expressions. Method XmlNode.SelectNodes returns a list of nodes selected by the XPath string.

node.selectSingleNode (patternString) This method returns an object for the first descendant node to match the specified pattern. The one parameter of this method is an XSL pattern query. If no match is made, it returns null. In the following example, we will use the SelectSingleNode () method to get the title of the feed.

Applies the specified pattern-matching operation to this node's context and returns the first matching node. public: virtual IXmlNode ^ SelectSingleNode (Platform::String ^ xpath) = SelectSingleNode; IXmlNode SelectSingleNode (winrt::hstring const & xpath); C#. public IXmlNode SelectSingleNode(string xpath); function selectSingleNode (xpath) I would expect that node.SelectSingleNode("//Job_Name") seeks for a tag named Job_Name only under the xml code represented by node. That is not what it seems to be happening, as it always return the same node, doesn't matter at what step of the foreach it is (i.e. the node selected from the nodes changes, but the node.SelectSingleNode("//Job_Name") always return the same content).
2015-09-16 · I guess it is because of those foreach-es and the long XML source. Do you have any suggestion how to optimize this code part? Sorry for my stupid questions, but I'm really new to C#. Am I right with this pairing: XmlNodeList class -> should use SelectNodes XmlNode class -> should use SelectSingleNode? Thank you 2012-06-27 · I'm trying to write a script that will look at a XML file and check to see if an Element exists. If it does exist then it looks at the child nodes to return the text of each of them. Whenever I run the script though I get an error: Line: 6 Char: 1 Error: Object variable not set Code: 800A005B Can anyone see what I'm doing wrong?
