areElementsEquivalent

public static boolean areElementsEquivalent(org.jdom.Element element1,
                                            org.jdom.Element element2)

isSyntacticallyEqual

public static boolean isSyntacticallyEqual(org.jdom.Element a,
                                           org.jdom.Element b)

author: Alberto Gonzales Compare two elements syntactically. This is done by recursively matching all subelements and attributes defined in OpenMath. Extra elements or attributes are ignored. If any of the elements is null, the result is "false". OM errors are treated specially: if the head symbol matches, they are considered equivalent regardless of the rest. This allows to match an error class ignoring the accompanying context information.

Parameters:

a - first element.

b - second element.

Returns:

true if equal, false otherwise.
