PHP Reading from a Source with Data

[stevesmename]

So I have a new company project, our company got these new Card Readers (swipe the card), it reads the sting decodes it with a simple php script, and then it runs a search on the member through an online database.

SO
1. Swipe
2. Decodes & Extracts, Member Number
3. Takes member number, and does FORM ACTION POST Search


Now, this is great!

But I want to go a little further, in the page source of the search field there is the following
[NOTE: I deleted confidential fields]

<!CDX BEGIN>
<!CDX RETURN_CD:0>
<!CDX MBR_ID:1020594>
<!CDX Mbr_Orig_Id:1020594>
<!CDX ASSOC_MBR_ID:>
<!CDX MBRS_PLS_IN:P>
<!CDX MBR_LST_NM:LASTNAMEHERE>
<!CDX MBR_FST_NM:FIRSTNAMEHERE>
<!CDX MBR_MID_INIT_NM:>
<!CDX MBRS_EXPIR_DT:EXPIRYDATEHERE>
<!CDX MBR_SLTN_CD:>
<!CDX MBR_NM_GEN_CD:>
<!CDX MBR_NM_SUFX_CD:>
<!CDX MBR_BSC_AD:ADDRESSOFCUSTOMERHERE>
<!CDX MBR_SUPL_AD:EXTRAADDRESSINFOHERE>
<!CDX MBR_ADR_CTY_NM:CITYOFCUSTOMERHERE>
<!CDX MBR_ADR_ST_PROV_CD:STATOFCUSTOMERHERE>
<!CDX MBR_ADR_PSTL_CD:ZIPCODEOFCUSTOMERHERE>
<!CDX MBR_TEL_NR:PHONENUMBERHERE>
<!CDX MBR_TEL_EXT_NR:>
<!CDX END>

Now like I said earlier this is in HTML Source.

Questions
1. What is this? xml?
2. Can I use this to extract the data with PHP? if so how?

So I would like to say just to give an idea:
$zipcode = $_GETfromFILE['ZIPCODE'];


I hope this makes sense

Any help is going to be very appreciated,
Thank you in advance for your help.

I found some information on the Server I'm trying to grab data from and found that the above code is surely XML file.

Now I just have one problem, How in the heck do I parse the XML into the PHP file?

so

$zipcode = MBR_ZIPCODEFROMXML

---------------
Right now I swipe the card, and it gives me an XML file with all the person's info. I want it so that I swipe the card get the xml file through php, query the information and make it available to move on to the next step.

So i can pull there first name, last name, address, and zip and fill them in the FORMS automatically (PLUS MANY OTHER HELPFUL THINGS!!)

----------------

So how do I read XML in PHP? I checked out php.net, that was confusing as hell.
