Question

I’m capturing data from the user and writing it to an xml string like so:

var myXml:XML =

{userEnteredText}

This is fine and dandy until the user gets cute with special characters like “& < >” etc. Illegal characters are also a problem like 0x19.

Is there are method that will sanatize my xml and encode special characters or will I have to roll my own?

Answer 1

simply converting the string to a textnode should do the trick

var s:String = "test<ie>test";
var x:XML = <xml/>;
x.appendChild(s);
trace(x.toXMLString());//outputs "<xml>test&lt;ie&gt;test</xml>"

also, you can stuff all the content into CTADA …

i’m not sure, why 0x19 should be illegal … whitespaces and nullbytes are often dropped … but if it is binary data you want, you should probably use base64 … >here’s a lib<
