I assume that comment was a PHP version, so you want something like this:
<?php
/**
* Strip bad xml chars
* @author phpzone
* @param string $in String passed by reference
* phpzone.co.uk
*/
function strip_invalid_xml_chars2( &$in )
{
$out = “”;
$length = strlen($in);
for ( $i = 0; $i = 0×20 && $current = 0xE000 && $current = 0×10000 && $current
I’ll try one more time, cut my post short last time, if it doesn’t work this time… oh well.
function strip_invalid_xml_chars2( &$in )
{
$out = “”;
$length = strlen($in);
for ( $i = 0; $i = 0×20 && $current = 0xE000 && $current = 0×10000 && $current <= 0×10FFFF):
// valid so leave “as is”
break;
default:
// invalid, so we set this char to a space
$in[$i] = ” “;
break;
}
}
// NOTE: doesn’t return a value as we worked purely on
// the string passed by reference, so don’t try catching a return value
}
there is something broken about this comment posting script, that code, is _not_ what I posted
The original is Java code. Thank you for the code you provided!
String str = “contains invalid chars”;
String stripped = str.replaceAll(“[^\\u0009\\u000a\\u000d\\u0020-\\ud7ff\\e0000-\\ufffd]“, “”)
