Converting a Java String to XML with escape characters

Thread view:

Hi,

I would like to convert a Java String to an XML formatted string with
escape characters. For example turning "&" to "&", "<" or "<",
and so on.

Is it possible to achieve this without resorting to external
libraries? (I'm using Java 5)

Thanks,
Luc

You'd have you write the code yourself, there isn't anything built
in. If you writting a JSP, the JSTL provides methods to escape, but
I'm assuming you're talkign about using the Java 5 Standard Edition

I think the easiest way (although not %100 perfect)

myString = myString.replaceAll("&", "&");
myString = myString.replaceAll("<", "<");

Alternatively, you could use CDATA escaping:
myString = "<![CDATA[" + myString.replaceAll("]]>", "]]>]]><![CDATA[")
+ "]]>";

There's also URLEncode/URLDecode, which works on the basic
encoding/decoding of strings.

Roedy Green's Entity Strip/Insert utility is a *very* complete
solution for this problem. Look here:

If you are wanting to do this so as it put the String into an XML --
why don't you just use a CDATA section in the XML removing the need to
escape the data.

How about using javax.xml.transform.Transformer ?

The transformer does not work on String directly. I insert my Strings
into a document and use Transformer to get my formatted string.

Cheers.
