DOMDocument appendXML with special characters

Question

I am retreiving some html strings from my database and I would like to parse these strings into my DOMDocument. The problem is, that the DOMDocument gives warnings at specia

Answer 1

There is no   in XML. The only character entities that have an actual name defined (instead of using a numeric reference) are &, <, >, " and '.

That means you have to use the numeric equivalent of a non-breaking space, which is   or (in hex)  .

If you are trying to save HTML into an XML container, then save it as text. HTML and XML may look similar but they are very distinct. appendXML() expects well-formed XML as an argument. Use the nodeValue property instead, it will XML-encode your HTML string without any warnings.

// document fragment is completely unnecessary
$otherElement->nodeValue = $row['message'];
