| Method Detail |
getChildElements
public static java.util.List getChildElements(org.w3c.dom.Node start)
- returns a java.util.List of Elements which are children
of the start Element.
hasChild
public static boolean hasChild(org.w3c.dom.Element start, java.lang.String name)
getChildElement
public static org.w3c.dom.Element getChildElement(org.w3c.dom.Node start, java.lang.String name)
getFirstChildElement
public static org.w3c.dom.Element getFirstChildElement(org.w3c.dom.Node start)
- gets the first child of a node which is an element. This avoids the
whitespace problems when using org.w3c.dom.node.getFirstChild().
Whitespace-nodes may also appear as children, but
normally are not what you're looking for.
getLastChildElement
public static org.w3c.dom.Element getLastChildElement(org.w3c.dom.Node start)
getNextSiblingElement
public static org.w3c.dom.Element getNextSiblingElement(org.w3c.dom.Node node)
- Returns the next sibling element of the specified node.
If there is no such element, this method returns
null.
getPreviousSiblingElement
public static org.w3c.dom.Element getPreviousSiblingElement(org.w3c.dom.Node node)
- Returns the previous sibling element of the specified node.
If there is no such element, this method returns
null.
getTextNode
public static org.w3c.dom.Node getTextNode(org.w3c.dom.Node start)
- gets the first child of a node which is a text or cdata node.
getTextNodeAsString
public static java.lang.String getTextNodeAsString(org.w3c.dom.Node start)
- returns the Text-Node child of Node 'start' as String. If no
TextNode exists, null is returned.

public static org.w3c.dom.Element getElementByAttributeValueNS(org.w3c.dom.Node start, java.lang.String tnuri, java.lang.String tagName, java.lang.String anuri, java.lang.String attrName, java.lang.String attrValue)
- equivalent to the XPath expression './/tnuri:tagName[@anuri:attrName='attrValue']'
getElementByAttributeValue
public static org.w3c.dom.Element getElementByAttributeValue(org.w3c.dom.Node start, java.lang.String tagName, java.lang.String attrName, java.lang.String attrValue)

getFirstChildByTagName
public static org.w3c.dom.Node getFirstChildByTagName(org.w3c.dom.Node contextNode, java.lang.String tag)

regardless of the depth in the tree.
getFirstChildByTagNameNS
public static org.w3c.dom.Node getFirstChildByTagNameNS(org.w3c.dom.Node contextNode, java.lang.String nsuri, java.lang.String tag)

selectNodesByPath
public static java.util.List selectNodesByPath(org.w3c.dom.Node context, java.lang.String nsuri, java.lang.String bindingExpr)
- Selects a nodelist for a path. the path is a simple slash seperated
path expression pointing to a node.
for a tree:
]]> the path is resolved always against a context node, and therefor may or may not begin with a slash.
