Constructor Detail

DocumentWrapperXPathNode

public DocumentWrapperXPathNode(org.w3c.dom.Document document)

Creates a new DocumentWrapperXPathNode

Parameters:

document - the Document that this XPathNode wraps. This must not be null.

Method Detail

getNodeType

public int getNodeType()

Returns the type of this node.

Specified by:

getNodeType in class org.exolab.adaptx.xml.dom2xpn.BaseDOMXPathNode

Returns:

The type of this node

getLocalName

public java.lang.String getLocalName()

Returns the local name of the node. Returns the local name of an element or attribute, the prefix of a namespace node, the target of a processing instruction, or null for all other node types.

Specified by:

getLocalName in class org.exolab.adaptx.xml.dom2xpn.BaseDOMXPathNode

Returns:

The local name of the node, or null if the node has no name

getNamespaceURI

public java.lang.String getNamespaceURI()

Returns the namespace URI the node. Returns the namespace URI of an element, attribute or namespace node, or null for all other node types.

Overrides:

getNamespaceURI in class org.exolab.adaptx.xml.dom2xpn.BaseDOMXPathNode

Returns:

The namespace URI of the node, or null if the node has no namespace URI

getStringValue

public java.lang.String getStringValue()

Returns the string value of the node. The string value of a text node or an attribute node is it's text value. The string value of an element or a root node is the concatenation of the string value of all its child nodes. The string value of a namespace node is its namespace URI. The string value of a processing instruction is the instruction, and the string value of a comment is the comment text.

Specified by:

getStringValue in class org.exolab.adaptx.xml.dom2xpn.BaseDOMXPathNode

Returns:

The string value of the node

getNamespaceURI

public java.lang.String getNamespaceURI(java.lang.String prefix)

Returns the namespace URI associated with this namespace prefix, as defined in the context of this node. Returns null if the prefix is undefined. Returns empty if the prefix is defined and associated with no namespace. This method is valid only for element nodes.

Overrides:

getNamespaceURI in class org.exolab.adaptx.xml.dom2xpn.BaseDOMXPathNode

Parameters:

prefix - The namespace prefix

Returns:

The namespace URI, or null

getNamespacePrefix

public java.lang.String getNamespacePrefix(java.lang.String uri)

Returns the namespace prefix associated with this namespace URI, as defined in the context of this node. Returns null if no prefix is defined for this namespace URI. Returns an empty string if the default prefix is associated with this namespace URI. This method is valid only for element nodes.

Overrides:

getNamespacePrefix in class org.exolab.adaptx.xml.dom2xpn.BaseDOMXPathNode

Parameters:

uri - The namespace URI

Returns:

The namespace prefix, or null

getFirstChild

public XPathNode getFirstChild()

Returns the first child node of this node, or null if the node has no children. Child nodes are only returned for an element or root node.

Overrides:

getFirstChild in class org.exolab.adaptx.xml.dom2xpn.BaseDOMXPathNode

Returns:

The first child node of this node, or null

hasChildNodes

public boolean hasChildNodes()

Returns true if this node has any child nodes.

Overrides:

hasChildNodes in class org.exolab.adaptx.xml.dom2xpn.BaseDOMXPathNode

Returns:

True if this node has any child nodes.

getNext

public XPathNode getNext()

Returns the next sibling node in document order, or null if this node is the last node. This method is value for any node except the root node.

Specified by:

getNext in class XPathNode

Returns:

The next sibling node in document order, or null

getPrevious

public XPathNode getPrevious()

Returns the previous sibling node in document order, or null if this node is the first node. This method can is valid for any node except the root node.

Specified by:

getPrevious in class XPathNode

Returns:

The previous sibling node in document order, or null

getFirstAttribute

public XPathNode getFirstAttribute()

Returns the first in a list of attribute nodes, or null if the node has no attributes. This method is valid only for the element node.

Specified by:

getFirstAttribute in class XPathNode
