Method Detail

selectNodes

public static NodeList selectNodes(String path,
                                   Object node,
                                   Map<String,String> namespaces)

Select all nodes that are selected by this XPath expression. If multiple nodes match, multiple nodes will be returned. Nodes will be returned in document-order,

Parameters:

path - the xpath expression

node - the starting node

namespaces - Namespaces that need to be available in the xpath, where the key is the prefix and the value the namespace URI

Returns:

result of evaluating the xpath expression against node

selectNodes

public static NodeList selectNodes(String path,
                                   Object node)

Select all nodes that are selected by this XPath expression. If multiple nodes match, multiple nodes will be returned. Nodes will be returned in document-order,

Parameters:

path - the xpath expression

node - the starting node

Returns:

result of evaluating the xpath expression against node

selectNode

                              Map<String,String> namespaces)

selectNode

public static Node selectNode(String path,
                              Object node)

                                Object node,
                                Map<String,String> namespaces)

Parameters:

path - the XPath to execute

node - the node, node-set or Context object for evaluation. This value can be null.

namespaces - the XML namespaces map

Returns:

the text of a node, or the value of an attribute

selectText

public static String selectText(String path,
                                Object node)

Parameters:

path - the XPath to execute
