edit XML with simpleXML

Question

How can I edit the value's in a xml file using simpleXML ?

I know how to create the file, but not how to edit the value in an existing file ?

Answer 1

I am working like this (it's quite the same but it could help): The file test.xml could be any extension as long as it's a plain xml text.

test.xml:

<?xml version="1.0" encoding="utf-8"?>
<sitedata>
    <Texts>
        <ANode SomeAttr="Green" OtherAttr="Small"/>This is the text I'm changing.</ANode>
    </Texts>
</sitedata>

And the PHP code:

$xml=simplexml_load_file("test.xml") or die("Error: Cannot create object");
$SomeVar="<b>Text. This supports html code.</b><br/>I also work with variables, like GET or POST.";
$xml->Texts[0]->{'ANode'}=$SomeVar;
$xml->asXml('test.xml');

Results test.xml:

<?xml version="1.0" encoding="utf-8"?>
<sitedata>
    <Texts>
    <ANode SomeAttr="Green" OtherAttr="Small"/>&lt;b&gt;Text. This supports html code.&lt;/b&gt;&lt;br/&gt;I also work with variables, like GET or POST.</ANode>
    </Texts>
</sitedata>

Hope it helps!
