html tags within xml tags

bumbar

I'm trying to find a way to put a block of html
within xml tags but it's not working. I think it's
looking at the html tags as if they were xml
tags. Here's an example of what I'd like to do.

<text>
some text 
some more text
another paragraph.
</text>

I'd like the content between the <text></text>
tags to come through as a string to be passed
along to the browser. Any suggestions with PHP parse?

Thanks in advance. 😕

You would need to ecsape the HTML tags to prevent them being treated as XML, for example

<text>
&lt;p&gt;some text&lt;p&gt;
</text>

The two functions html_entities() and html_entity_decode() can help you here.

Here problem: Script stopped were occur "" tag!

NogDog

Please see my first reply: you must use the CDATA delimiters for values that might otherwise be interpreted as XML mark-up.

Thank you, NogDog! XML file is not my own! I get this file from internet and I have not permitions to include <![CDATA[sometext]]>. Or I must create DTD file ...

Weedpacket

Well then, whoever is making is is making broken XML. Consider complaining about it.

Or do some preprocessing: when reading the stream find the tags that might contain HTML, and replace <text> with <text><![CDATA[ and </text> with ]]></text>, before sending it on to the XML parser (in your code you'd be doing this to $data).

bumbar

I resolve problem with <![CDATA[sometext]]>.
I just set up function str_replace(). I looping entire XML document with that function and replace tags. Automatic every document. Right!
Thanks! 😉
