Topic:
PHP Scripting Language;Programming Languages;Web Applications
I'm needing to modify the value of a specific XML node with php, but I keep getting this error with the following code:
Catchable fatal error: Argument 1 passed to DOMNode::replaceChild() must be an instance of DOMNode, string given in...
/*Here's the XML Structure:*/
Catchable fatal error: Argument 1 passed to DOMNode::replaceChild() must be an instance of DOMNode, string given in...
/*Here's the XML Structure:*/
<pages> <page> <contents>A bunch of text here </contents> </page> <page> <contents>A bunch of text here </contents> </page> <page> <contents>A bunch of text here </contents> </page></pages> 1:2:3:4:5:6:7:8:9:10:11:12:13:14:
/*And here's the code I'm trying to use to edit specific content nodes*/
$data = new DOMDocument('1.0', 'utf-8');" $data->"formatOutput = true;" $data->"preserveWhiteSpace = true;" $data->"load('../data.xml');" //load elements $page = $data->"getElementsByTagName('page')->"item(0);" $contents = $page->"getElementsByTagname('contents')->"item(0);" $contents = $string;" //This is a string variable $page->"replaceChild($contents, $contents);" //This is the line that produces the error 1:2:3:4:5:6:7:8:9:10:11:12:13:
So I'm not sure if my overall approach is wrong, or if I just need to modify the string variable make it an instance of DOMNode. Please Help! Thank you!

This looks like a very theoretical and redacted example. It may be helpful if you have a better test case. But that aside, here is how you can do it. Please copy this, install it on your server and run it to see the output, and please post back if you still have any questions. Best regards, ~Ray

Try this
$data = new DOMDocument('1.0', 'utf-8'); $data->formatOutput = true; $data->preserveWhiteSpace = true; $data->load('../data.xml'); //load elements $page = $data->getElementsByTagName('page')->item(0); $contents = $page->getElementsByTagname('contents')->item(0);$contents->nodeValue=$string; 1:2:3:4:5:6:7:8:9:10:

Please read the manual and example for replaceChild() in php.net, it is used to replace it to
new node at http://php.net/manual/en/domnode.replacechild.php

Once you execute this statement:
$contents no longer points to the node.
Delete or comment that statement and try this version of the replaceChilld() statement.
$page->replaceChild($contents, $string); //This is the line that produces the error 1:
