RSS feed syntax issue in str_replace

[dbrimlow]

I took over an application that sends an RSS feed with ads to craigslist.

 

The following is part of a str_replace that looks wrong to me, but I can't test it to check because it is not on a development server (only live).

 

The sibling "<![CDATA" of the named parent "<cl:previewHTML>" below is closed last, evan after the RDF root has closed. Can that be right under any circumstances?

 

Here is how it is:

 

$data1 = str_replace("<cl:previewHTML><![CDATA[", "", $data1);

$data1 = str_replace("</cl:previewHTML>", "", $data1);

$data1 = str_replace("</item>", "", $data1);

$data1 = str_replace("</rdf:RDF>", "", $data1);

$data1 = str_replace("]]>", "", $data1);

 

Wouldn't it need to be closed before its parent closes under any circumstances? Like:

 

$data1 = str_replace("<cl:previewHTML><![CDATA[", "", $data1);

$data1 = str_replace("]]>", "", $data1);

$data1 = str_replace("</cl:previewHTML>", "", $data1);

$data1 = str_replace("</item>", "", $data1);

$data1 = str_replace("</rdf:RDF>", "", $data1);

 

Is there enough of the code shown to determine, or do I need to post the whole concatenation?

 

Thanks
