So I know I can write my own HTML-encoding function like this:
function getHTMLEncode(t) {
return t.toString().replace(/&/g,"&").replace(/"/g,""").replace(/</g,"<").replace(/>/g,">");
}
But I was wondering if there were any native facility for this that is available to XPCOM components. I’m writing a component, not an overlay, so I don’t have a DOM around to do tricks like creating a DOM element and setting its innerHTML.
The answer appears to be no – there is no built in function in Firefox to HTML-encode a string from an XPCOM component.
