• Query for a document. Note that queries can be formed against an individual document, or against multiple documents.
• Query for document subsections, including values found on individual document nodes.
• Manipulate and transform the results of a query.
• Modify a document (see Modifying XML Documents for more information).

To do this, XQuery views an XML document as a collection of element, text, and attribute nodes. For example, consider the following XML document:

CopyXML

<?xml version="1.0"?>
    <Node0>
      <Node1 class="myValue1">Node1 text </Node1>
      <Node2>
        <Node3>Node3 text</Node3>
        <Node3>Node3 text 2</Node3>
        <Node3>Node3 text 3</Node3>
        <Node4>300</Node4>
      </Node2>
    </Node0>

In the above document, <Node0> is the document's root node, and <Node1> is an element node. Further, the element node, <Node1>, contains a single attribute node whose name is class and whose value is myValue1. Finally, <Node1> contains a text node whose value is Node1 text.
