Reading XML Response

[Dustin013]

What is the correct method for reading an xml response from a server that replies using a small XML file in response to a post request sent from a form?

<!DOCTYPE response SYSTEM "https://blah/ap/dtd/response-v2.dtd">
<response>
    <result>success</result>
    <data>data here</data>
    <Id>0000</Id>
    <url><![CDATA[https://blahblah.com/lead?action=show&variable=0000]]></url>
</response>

simplexml

 

Would be my answer.

Ok, I have a form, it makes a post to a URL, can you give me an example of how I am going to be able to get the script to read the response? I can see the response as shown above in Firebug, but I am trying to figure out how to get the script that is submitting the form to read the response. I know how to parse the data but not exactly sure how to grab the information the server is responding with.

Your script really needs to act as a client, submitting the form contents via a POST and then accepting the response from the server.  This is quite complicated stuff.  The best advice I have is to use PHP's curl integration. 

 

http://www.php.net/curl

 

 

Basically what you would need to do:

 

1. Form posts either to itself or to another script

2. Use Curl to re-post to the target server

3. Curl will let you read the response data

4. Parse that into something you can use with simplexml or whatever other PHP/xml solution suites you.

Thanks for the help, I ended up using the following...

 

$xmlFileData = file_get_contents($url);

$xmlData = new SimpleXMLElement($xmlFileData);

 

etc.. and got it to work great ;-)
