Summary: This video continues our discussion of XML by finishing up the application we started in lesson III. We add a textbox to the form that allows the user to enter a tag name. When the user clicks the “Select Tag” button (also added to the form), we use the Document’s getElementByTagName method that returns for us an XmlNodeList of all the matching nodes. For every one of those matching nodes, we look for a match in the TreeNode. If we get a match, we change the font of that node in the tree (we make them bold).
