Processing an XML document in Javascript

[Sebarry]

Hi,

I have a Javascript function that creates a Ajax request to retrieve data from a database using a PHP script. The data returned by the PHP script is an XML Document that I access through transport.responseXML. The structure of the XML document is as follows:

<job>
<contactTelephone>028 ---------</contactTelephone>
<contactName>Karen -------</contactName>
<contactFax>028 -----------</contactFax>
<contactEmail>karen@---------</contactEmail>
<contactWebsite>www.---------</contactWebsite>
</job>

I use var xmlOptions = xmlDoc.getElementsByTagName('job'); to get job and then xmlOptions[0].getElementsByTagName('contactTelephone')[0].firstChild.data but can I use a for loop to process the XML document tag by tag without hardcoding it? Using a variable in getElementsByTagName?

Thanks,

Sean
