Constructor Detail

DOMXPath

public DOMXPath(java.lang.String path)

Creates a new DOMXPath object.

Parameters:

path - string form of an XPath

Method Detail

solve

protected java.lang.Object solve(java.util.List path)

Returns the value of the first TEXT_NODE. The whitespace is deleted from the value

Specified by:

solve in class XPath

Parameters:

path - The list of the nodes from the root (Not necessarily doc node) and the identified node. Only the last node is actually used in the calculation.

Returns:

the value of the first TEXT_NODE. The whitespace is deleted from the value

getChildren

protected java.util.Iterator getChildren(java.lang.Object o)

returns an iterator that iterates through all the o's children that are Element objects

Specified by:

getChildren in class XPath

Parameters:

o - A Node element

Returns:

an iterator that iterates through all the o's children that are Element objects

getNodeName

protected java.lang.String getNodeName(java.lang.Object o)

Returns the node name of the node. Uses getNodeName()

Specified by:

getNodeName in class XPath

Parameters:

o - A Node object

Returns:

the node name of the node. Uses getNodeName()

isLegalNode

protected boolean isLegalNode(java.lang.Object o,
                              int operation,
                              boolean isList)

Description copied from class: XPath

Tests whether the object passed is a legal node element Legal nodes may differ depending on the type of operation being performed.

Specified by:

isLegalNode in class XPath

Parameters:

o - Object to test

operation - one of the OP_XXX constants

Returns:

true if object o is a valid node object
