Using PHP - How to create a variable in XML?

[Chrex 0]

Hi guys,

I try to build an xml document with php. Creating, saving and sending works fine. Just couldnt figure out how to insert a variable to my php-code, which creates the xml.

<?php$xml = new DOMDocument("1.0", "utf-8";$root = $xml->createElement("ABC");$xml->appendChild($root);$var1 = $xml->createElement("Town");$var1Text = $xml->createTextNode('$townname');$var1->appendChild($varText);$BCD = $xml->createElement("Data");$BCD->appendChild($var1);$root->appendChild($BCD);$xml->formatOutput = true;echo "<xmp>". $xml->saveXML() ."</xmp>";$xml->save("energieausweis.xml") or die("Error");?>

Instead of using a fix "createTextNode" I wanna use a variable. Something like "createVariableNode" (I know that this doesnt exist).

Hope you guys understand me. I get a variable from a form, lets say $townname, which can be Vancouver or Paris. This variable shall be written in my xml. Depending on the selection from the form, my xml shall contain Vancouver or Paris and not just the text "$townname".

 

Thanks a lot for your help!

The XML language doesn't have variables.

 

If you want the contents of a PHP variable in your XML document, just pass the variable to the function:

$value = 'Some text';$textNode= $xml->createTextNode($value);

When using variables in PHP you don't wrap them in quotation marks, especially not single quotes. In PHP single quotes print out literally what is between them. Double quotes print text, special characters and variables. If all you want is the value of the variable itself, then don't use any quotation marks at all. The variable has the value in it already.

Thanks for the hint!

I took my value from the session and did it like this:

	$value = $_SESSION['name'];	$valueText = $xml->createTextNode($value);

It works

You could even put $_SESSION['name'] right in the function.
