I think it urldecodes them into spaces or something. No time to upgrade.... Yeah, sorry about that — WP has a bug with plus signs. I think it urldecodes them into spaces or something.

I need to profile some stored procedures, and this will do just the trick. Thanks for this great UDF. I need to profile some stored procedures, and this will do just the trick.

The greater than sign is usually printed literally but most parsers assume that the less than sign is the start of a new tag. A trick that sometimes work is to put everything inside pre inside a CDATA section: <pre>&lt![CDATA[ #include <stdio.h> ... ]]></pre> Hi Baron,

“I thought it usually handled that inside ‘pre’ tags”

The best thing of pre is that it treats all white space as significant white space:

http://www.w3.org/TR/REC-html40/struct/text.html#h-9.3.4

However, the contents are still parsed as HTML. The greater than sign is usually printed literally but most parsers assume that the less than sign is the start of a new tag.

A trick that sometimes work is to put everything inside pre inside a CDATA section:

<pre>&lt![CDATA[

#include <stdio.h>

…

]]></pre>

And, thanks for the link to the UDF repository page ;-) I just wanted to let you know that the code sample does not render the #include lines properly - you probably should escape the angle brackets #include &lt;stdio.h&gt; Hi Baron,

thanks for sharing this code! And, thanks for the link to the UDF repository page ;-)

I just wanted to let you know that the code sample does not render the #include lines properly - you probably should escape the angle brackets

#include &lt;stdio.h&gt;
