* xmlXPathLeadingSorted: * @nodes1: a node-set, sorted by document order * @nodes2: a node-set, sorted by document order * * Implements the EXSLT - Sets leading() function: * node-set set:leading (node-set, node-set) * * Returns the nodes in @nodes1 that precede the first node in @nodes2 * in document order, @nodes1 if @nodes2 is NULL or empty or * an empty node-set i

 *         an empty node-set if @nodes1 doesn't contain @nodes2
