Sending XML file through PHP remote url - php

Question

The situation is as follows. I have to send a defined XML to an url http:\\www.example.com:1234 with some variables that I have to previously define.
XML is like this:
<Title1>
<Title2>Some Text</Title2>
<Title3>Variable 1</Title3>
<Title4>Some Text</Title4>
<Title5>
<Title51>Variable 2</Title51>
</Title5>
</Title1>
But, I want to define those variables (1, 2) within an html/php form and get method, so the user can introduce both variables and then click on the submit button from the form to send the XML to the previously URL.
Also, XML should have the "Content-Type","application/x-www-form-urlencoded" header.
Is this possible? I've tried to pass these variables directly to the XML and the best that I've come to is to showing the XML and not parsing the php strings.
Also, I've tried some scripts like simplexml from PHP classes, but with no luck so far.

Answer 1

1) To modify existing XML with new values . Try this
sample.xml :
<Title1>
<Title2>Some Text</Title2>
<Title3>Variable 1</Title3>
<Title4>Some Text</Title4>
<Title5>
<Title51>Variable 2</Title51>
</Title5>
</Title1>
PHP :
$xml = simplexml_load_file("sample.xml");
$xml->Title3 = $_GET['t3']; // Updating <Title3></Title3> from GET method
$xml->Title5[0]->Title51 = $_GET['t5']; // Updating <Title51></Title51> from GET method
$xml->asXML('sample.xml'); // saving the xml file
2)To create new XML file (sample.xml) :
PHP:
$xml = new SimpleXMLElement("<Title1></Title1>");
$xml->Title2='Some Text';
$xml->Title3 = $_GET['t3'];
$xml->Title4='Some Text';
$xml->Title5[0]->Title51 = $_GET['t5'];
$xml->asXML('sample.xml'); // saving the xml file
I have showed you both possibilities mentioned in the comment . Use anyone which comforts you :)
