changing the values of xml nodes using PHP

[mr_burns]

Hi there,

Is it possible to use PHP to change the values of XML nodes in an XML
file witout having to extract all the node values, change the variable
I want, use PHP to generate the node structure and then save it as an
new XML file?

For example, say I have the following XML structure in an XML file:

<xml...
<settings>
<width>400</width>
<hieght>500</hieght>
<color>blue</color>

Is it possible to just use PHP to find the node 'width', change it to
600 and then resave the XML file? Cheers

Pretty easy with regular expression:

$xml = file_get_contents($filename);
$xml = preg_replace('/<width>.*?<\/width>)/i', "<width>$width</width>",
$xml);
fwrite(fopen($filename, 'wb'), $xml);

xml);

hi,

i tried the above and got an error. after reading up on regular
expressions i fixed it with the following:

$xml = preg_replace('(<width>.*</width>)', "<width>$width</width>",
$xml);

i havent included the parts such as '.*?', '/i' as well as a few
slashes. are these required?
