A Final Word

In this column we continued our series on Web services. This is the fourth in a miniseries about XML loading and manipulating of the DOMDocument object. We focused in this column on methods for selecting nodes from the DOMDocument tree. We explained to you the concept of context and that the context is determined by the node. We showed you how to select nodes with the selectNodes() and selectSingleNode() methods. We covered more than a dozen search patterns for nodes. We gave you both the JavaScript code as well as a demo for each of these patterns.

In this column you have learned:

• How to define context - Part A
• How to define context - Part B
• How to select nodes
• How to specify patterns - Part A
• How to specify patterns - Part B
