Parsing an XML return from a POST

[Richard Luckhurst <rluckhurst@xxxxxxxxxxxxx>]

Hi List

I am working owards completing a rather urgent project for one of our clients.
There is a requirement to send a request to a server and I now have that working
using cURL, thanks to help from this list. I now have the responses coming back
as an XML response. What I need to do is to parse the XML response and break it
up into either an array or variables so I can pass the returned responses back
to a calling process.

I have spent most of last night and today looking at XML parsing and now am
totally confused. Some testing I have done suggests that SimpleXML is not the
way to go however I am open to suggestions if it might be an answer. I would
appreciate any help or advice on how to parse this XML response and break it up
into either an array or individual variables.

I have included a sample response from the server below. A few points to be
aware of,

1) In the fares section there could be any number of fares however each fare
will have a fareID and then the fareBases child.
2) In the tarifs section there could be any number of tarifs however each tarif
will have a tarifId and then 1 or more fareXrefs.
3) In the vcrSummary section there could be 1 or more vcr entries
4) The response comes back as one long string and I have formatted this to make
it a little easier to read.

<?xml version="1.0" encoding="UTF-8"?>
<?ypsilon RNGSchema="fareResponse.rnc" type="compact"?>
<fareResponse cntTarifs="122" offset="0">
  <fares>
        <fare fareId="11429927" fareType="PUB" checked="false" class="V" depApt="SYD" dstApt="LON" paxType="ADT" vcr="OS" cos="E" yyFare="false" avail="false">

  </vcrSummary>
</fareResponse>

  
I would certainly appreciate any help I can get. Thanks in advance.
