First, let me clear up a misconception you seem to have. Elements, such as the
ones denoted by the <a> and <b> tags, do not have values, although they may
contain attributes which have values (such as <a length="42">). The value of any
attributes can be obtained with the handler that you specify with
XML_SetStartElementHandler() (see the documentation). The text contained between
a start and end tag such as the "hola" in <a>hola</a> is called character data,
and does not technically have any relation to the tag, except as far as
validation using the DTD is concerned. This character data can be obtained using
the handler that you specify with XML_SetCharacterDataHander() (again, see the
documentation). The only way to tell what tags the character data occured inside
of is to keep track of which tags you are parsing inside of your
StartElementHandler() function and your EndElementHandler() function.
