To prevent a parser error when the comment string would contain the character sequence "--", do this:


= 'This contains -- some weird -- characters.';

$CommentNode = $DomDocument->createComment(
str_replace('--', '-'.chr(194).chr(173).'-', $CommentString)

This will insert a Soft Hyphen in between the two hyphens which will not cause the parser to error out.

Use caution: this function does NOT escape, encode, or otherwise change the contents of the string.

This means that if your string contains two hyphens in a row (--), that will *end* the comment, which can easily create invalid XML when the document is serialized.
