well i would start by not putting all that whitespace in your string to start with.

I am also trying to place xquery string in heredoc .. see nearby thread

I note that you are using "XML" as the delimiter in

$xmlstr =<<<XML

I'm sure that this delimiter must be a unique keyword not appearing in the body .. and you have "<?xml" on the next line.

heredoc is very sensitive to white space.

[saeed99]

hi

its php5.0.4

[Weedpacket]

What would your XML file look like if it was "trimmed"?

<?xml version="1.0" encoding="UTF-8"?>
<test>
<question id="2" >
<answer id="25" >
<result>Wrong</result>
<mark>0</mark>
<symbol>an18</symbol>
</answer>
</question>
</test>
