Patch and structure question

I'm planning on solving easy things for now to get my feet wet. Question about structure, comparing the simplexml documnet i've been working with to the structure provided as a framework: the framework shows <title><function>functionname</function> example</title> <programlisting role="php"> simplexml shows <title>Include file example.php with XML string</title> <programlisting role="php" xml:id="simplexml.examples.movie"> Which one should I be using, there are two questions here, the function tags surrounding the function name, and the xml:id bit. also, please comment on patch attached. One question I ran into while working on it, was wether I should be using var_dump() to illustrate the function, or some sort of an if structure. var_dump() makes the most sense to me, but it has the requirement of understanding what it is.... paul -- Paul Reinheimer Zend Certified Engineer
