DOM XML woes

elenev

I have just installed DOM XML functions and I am trying to do $dom = xmldocfile("example.xml")

However PHP gives me the following errors:
Warning: warning: in d:\inetpub\wwwroot\test.php on line 13

Warning: failed to load external entity "example.xml" in d:\inetpub\wwwroot\test.php on line 13

I simplified my XML file to the minimum and made sure that it can be fopen'ed, file'd and xml_parse'd, but neither xmldocfile(), xmldoc() or domxml_open_file() work.

HELP!!!!

I hope I've responded before all your hair is missing...

Ok... the reason is because you need to say the EXACT path..

ie.. if your xml file resides in c:\web\xml\example.xml you need to say...

$dom = xmldocfile("c:\web\xml\example.xml")

note the double slashes! Very important on a windows platform.

You could help me in return by mentioning any XML DOM resources that you might have found a little bit useful - there is very little documentation on the web for XML DOM, and I'm still learning too.

BTW - there are differences between the new and old versions of XML DOM - I don't understand what they are yet, but the older code is not compatible with the newer DOM if you know what I mean.

Good Luck!

Try Zvon - I found several megabytes worth of stuff there. Or the obvious W3C (home of all the standards like HTML/XHTML, CSS, DOM and XML) and XML.org, the latter hosted by Oasis. "Very little documentation" he says

And note of course that PHP's documentation warns that DOM XML support is Experimental - "Be warned and use this extension at your own risk." - so don't be surprised if it's flaky.

Has anybody used the results from DomDocument->get_element_by_id?

I've been experimenting on and off with this extension and have been working on a web based XML editor. I know that it is all still experimental, but some day all of this will work and I want to know how to do it all when the time comes.

If you do use the get_element_by_id, you will need to tell the XML parser what attribute is the ID, simply naming the attribute ID won't work. This bit of code works:
<!DOCTYPE imadethisup [
<!ATTLIST user id ID #REQUIRED>
<!ATTLIST game id ID #REQUIRED> ]>

Just replace the 'user' and 'game' with the appropriate tag names and the id (not the ID) with the appropriate attribute name. Add as many ATTLIST's as you need. I have not tested but I suspect that you could also just use a external DTD too.

I hope that helps someone, and I hope that someone can help me. Once I've found the Node that I'm searching for the function returns a DomElement. Like this:
$result = $dom->get_element_by_id("11");

I can get the node's tag name like this:
echo $results->tagname;

But what I want to get is the value of the node. DomNode->node_value does not return anything.

Does anyone have any idea what I'm doing wrong?
