I'm trying to parse an XML document. The document in question is an AppxManifest file.
An example document looks like this:
<?xml version="1.0" encoding="utf-8"?>
<Package xmlns="http://schemas.microsoft.com/appx/2010/manifest" xmlns:build="http://schemas.microsoft.com/developer/appx/2012/build" IgnorableNamespaces="build">

I try to parse it like so:
var xml=new XmlDocument();
xml.Load(myfile);
var mgr=new XmlNamespaceManager(xml.NameTable);
mgr.AddNamespace("", "http://schemas.microsoft.com/appx/2010/manifest");
var nodes=xml.SelectNodes("Applications");
However, after I execute this, nodes
will never contain anything. The xml document is loaded and such though. using SelectNodes("//*")
returns every node as expected. What is my problem here?
I've also tried many variations on that XPath query such as
/Package/Applications/Application
Applications/Application
Applications/*
Nothing appears to retrieve the single node though. Ideally, I'd like for nodes to contain all of the Application
nodes
You have to use xml namespace specifically to select them. consider
"//*[local-name()='Applications']/*[local-name()='Application']"
in your case this code may also work well:
var doc = new XmlDocument();
doc.LoadXml(xml);
var nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("a", "http://schemas.microsoft.com/appx/2010/manifest");
var nodes = doc.SelectNodes("//a:Applications/a:Application",nsmgr);
