The GetAttribute(xmlTree, attrName) command retrieves the value of the attribute attrName from the XML element xmlTree as a Maple equation.  If the specified attribute is not present, then the value FAIL is used as the right-hand side of the returned equation.

Note: The presence of an attribute with a given name is tested by using HasAttribute.
