php scripting in xml documents

[Anon]

How do you get php to execute before the xml parser parses the document?

Like this

<mytag><?php echo 'hey'; ?></mytag>

Thanks in advance.

I think you want to check out the xml_set_processing_instruction_handler() function. Let me know if this is right, I'm getting into working with XML documents and could use any insight...

Well, that just returns \'php\' and \"echo \'Hey\'\"

How do you tell php to execute this stuff?

Well, you can go,

if( $target == \'php\' ) {
eval( $data );
}

inside your defined PI handler function. That will execute the code, but how do i get it to have properly?

<b>Stuff:</b> <?php echo \'hey\'; ?><br />

That line will print hey before the rest of the stuff because the parsing doesn\'t output anything, it simply constructs an object. How do i get it to hey in replace of the php code?

This kind of defeats the purpose with all this stuff, no?

<tag>Stuff: </tag>
<?php
$this->addHtmlTag( new Text( \'Hey, PHP Put Me Here\' ) );
?>
<br />

No, not really. If you have an XML doc with all the tags and so forth, when the parser comes across <?php echo "hey" ?> then the PI handler should run it. I do kinda agree with you, it does seem to defeat a purpose though. Im'm getting into my XML project today (read purchase orders, insert into database) and if you're urious, I'll letcha know what I find out...
