Parsing XML: how to retrieve 'inner HTML' ?

[realtebo]

I'm parsing the api dump in xml of jquery doc (api.jquery.com/api).

parameter description and long description of call contains often 'code' tag, and similar html tag.

So, my idea was to retrieve with xpath->evaluate the content of the dom node, but using nodeValue the html will be loosen. Only text note will be retrieved.

is there a way to ready the entrire content of a tag without altering its content ?

follow an example

<desc>A map of additional options to pass to the method. Supported keys:
        <ul>[*]<code>duration</code>: A string or number determining how long the animation will run.[*]<code>easing</code>: A string indicating which easing function to use for the transition.[*]<code>complete</code>: A function to call once the animation is complete.[*]<code>step</code>: A function to be called after each step of the animation.[*]<code>queue</code>: A Boolean indicating whether to place the animation in the effects queue. If <code>false</code>, the animation will begin immediately.[*]<code>specialEasing</code>: A map of one or more of the CSS properties defined by the properties argument and their corresponding easing functions (added 1.4).[/list]
        </desc>

I want to save into a string the full inalterated content of 'desc' tag. Included <ul>,[*], etc.. tags...

How to ?

Perdonatemi se ho scritto in inglese, è l'abitudine ....

volevo sapere se c'è un modo per ottenere il contenuto di un nodo, compresi tutti i suoi figli eventuali, ma con i tag e tutto, tipo un innerHTML per intenderci...
