Escaping < in templates
1 March 2012 at 12:18am Last edited: 1 March 2012 12:19am
I'm outputing an XML file for excel which requires second line:
<?mso-application progid="Excel.Sheet"?>
I've looked around for a couple of hours but can't find a reference to the escape character for "<" and ">" in the templates, to stop silverstripe converting it to:
SSVIEWER;
mso-application progid="Excel.Sheet";
$val .= <<<SSVIEWERCan somebody let me know the correct method of displaying the line literally?

I've gone with an alternative solution to my problem for now. I've gone into the SSViewer.php code in sapphire/core and added some lines to the parsing code. The code treats the xml header beginning "<?xml" as a special case and I've added lines to do the same to my "<?mso-application" lines.
$content = ereg_replace('<\?xml([^>]+)\?' . '>', '<##xml\\1##>', $content);
$content = ereg_replace('<\?mso-application([^>]+)\?' . '>', '<##mso-application\\1##>', $content);$output = ereg_replace('<##xml([^>]+)##>', '<' . '?xml\\1?' . '>', $output);
$output = ereg_replace('<##mso-application([^>]+)##>', '<' . '?mso-application\\1?' . '>', $output);It does work, but I don't like playing with the core code like this. If somebody can suggest an alternative solution, such as a way of escaping my '<' or '?' characters to print my mso-application line, it would be a big help.
