public static org.w3c.dom.Document parseString(java.lang.String xml) throws java.io.IOException, org.xml.sax.SAXException, javax.xml.parsers.ParserConfigurationException
java.io.IOException
org.xml.sax.SAXException

public static java.lang.String getAttribute(org.w3c.dom.Element e, java.lang.String name)
The DOM getAttribute method returns an empty string if the attribute doesn't exist. Here, we detect this and return null.

public static org.w3c.dom.Element getFirstChildElement(org.w3c.dom.Node node)
node
- The node. May be null.public static org.w3c.dom.Element getNextElement(org.w3c.dom.Node node)
public static java.lang.String getContent(org.w3c.dom.Element e)
We will descend to an arbitrary depth looking for the first text node.
Note that the parser may break what was originally a single string of pcdata into multiple adjacent text nodes. Xerces appears to do this when it encounters a '$' in the text, not sure if there is specified behavior, or if its parser specific.
Here, we will congeal adjacent text nodes.
We will NOT ignore text nodes that have only whitespace.
