How to use Node Test in XPath Axes using Xml
In this article I will explain how to use the Node Test in XPath axes.
In my previous article I will explain the axis syntax ,In which we use the Node Test. In this article I will explain how to use the Node Test and why. Node test is part of an expression that is used to retrieve one or more nodes. The syntax is,
AxisName :: Node_Test [predicates]
Hear predicate is optional term. In my previous article I will explain the Name of axis now in this we see the Node_Test.
child :: title
Hear title is the node_test, In addition to this, ( wildcards, name of the node) the node_test can be one of the following
- comment() : It is used to selects nodes that are comments.
- node() : It is used to selects nodes of any type.
- processing-instruction() : It is used to selects nodes that are processing instructions. We can specify which processing instruction to select by providing it's name in the parentheses.
- text() : It is used to selects a text node.
