Using Document Object Model

How do I read the attribute name and value of an element

ie

<Book PUBLISHER="Wrox">

The Beginning XML Book only outlines how to read node values. Which I have no trouble doing but I do not know how to read attribute names/values.

Thanks

There are a number of ways, assuming <Books> as the root element, here are two.

• Code:

  var oNode = oDom.selectSingleNode("/Books/Book/@PUBLISHER");
  var sPublisher = oNode.nodeValue;

• Code:

  var oNode = oDom.selectSingleNode("/Books/Book");
  var sPublisher = oNode.getAttribute("PUBLISHER");

If the attribute name isn't namespaced, then the simplest method to get its value (in DOM) is

getAttribute("PUBLISHER")

applied to the Element representing the Book.

I'm a little surprised that you should have difficulty finding this in the documentation, so perhaps I misunderstood your problem.
