rss & html entities

I'm trying to syndicate my news system into the rss format, but there is a problem when there is an html entity in my news content. here is an exemple of error message I get:

Code:

Reference to undefined entity 'agrave'. Error processing resource 'http://localhost/mytest/index.rss'. Line 5, Position 17 
 

  <title>Tarte &agrave; la fraise</title>
----------------^

Here is the source code:

Code:

<?xml version="1.0"?>
<rss version="0.91">
	<channel>
		<title>Tarte &agrave; la fraise</title>
		<link>http://localhost/mytest/</link>
		<description></description>
		<lastBuildDate>Mon, 03 Feb 2003 15:55:02 GMT</lastBuildDate>
		<docs>http://backend.userland.com/rss091</docs>
		<managingEditor></managingEditor>
		<language>en</language>

				<item>
			<title>This is a title!</title>
			<description>This is<br>a<br><br>body.</description>
			<link>http://localhost/mytest/index.php?action=viewcom&id=37</link>
		</item>
	</channel>
</rss>

Can anyone please help? Thanks.

The simplest way is to replace your entities with ascii hex codes. à = %E0.

Here's a list (scroll down) http://www.bbsinc.com/iso8859.html

They render exactly the same as the html entities, but don't need to be defined in xml.

A timely topic for me too.

My rss generating script (created by jpenn -- php forum) encountered an "&" and choked. I tried htmlentities() and htmlspecialchar() in the hope of sliding by, but no dice.

I'm assuming that we must create a mega preg_replace script like the one below except replacing with ascii?

PHP Code:


		
			
// $document should contain an HTML document.

// This will remove HTML tags, javascript sections

// and white space. It will also convert some

// common HTML entities to their text equivalent.



$search = array ("'<script[^>]*?>.*?</script>'si",  // Strip out javascript

                 "'<[\/\!]*?[^<>]*?>'si",           // Strip out html tags

                 "'([\r\n])[\s]+'",                 // Strip out white space

                 "'&(quot|#34);'i",                 // Replace html entities

                 "'&(amp|#38);'i",

                 "'&(lt|#60);'i",

                 "'&(gt|#62);'i",

                 "'&(nbsp|#160);'i",

                 "'&(iexcl|#161);'i",

                 "'&(cent|#162);'i",

                 "'&(pound|#163);'i",

                 "'&(copy|#169);'i",

                 "'&#(\d+);'e");                    // evaluate as php



$replace = array ("",

                  "",

                  "\\1",

                  "\"",

                  "&",

                  "<",

                  ">",

                  " ",

                  chr(161),

                  chr(162),

                  chr(163),

                  chr(169),

                  "chr(\\1)");



$text = preg_replace ($search, $replace, $document);

as is shown in the manual http://www.php.net/manual/en/function.preg-replace.php
or is there a more direct way?
