Actually, I added these two:
public void setAttributeWithValue(String xpath, String value) throws
DOMException {
Element msgXML = getContent();
if(msgXML!=null) {
Attr attribute = msgXML.getAttributeNode(xpath);
if(attribute==null)
throw new DOMException(DOMException.NOT_FOUND_ERR,
"Attribute not found in message with xpath: "+xpath);
else
attribute.setValue(value);
}
}
public void setAttributeWithAttribute(String xpathToSet, String
xpathValue) throws DOMException {
Element msgXML = getContent();
if(msgXML!=null) {
Attr attributeToSet = msgXML.getAttributeNode(xpathToSet);
Attr attributeValue = msgXML.getAttributeNode(xpathValue);
String faultMsg = "";
boolean fault = false;
if(attributeToSet==null) {
faultMsg = "Attribute not found in message with xpath:
"+xpathToSet+"/n";
}
if(attributeValue==null) {
faultMsg += "Attribute not found in message with xpath:
"+xpathValue+"/n";
}
if(fault)
throw new DOMException(DOMException.NOT_FOUND_ERR,
faultMsg);
else
attributeToSet.setValue(attributeValue.getValue());
}
}
