Unescape escapeXML text

[Robert Mark Bram]

Hi All,

I have an application that is writing Javascript with JSP server side
code that uses escapeXML:

var someVar = "<c:out escapeXml="true " value="You'll never escape!"/

>";

How to I unescape this? Using the unescape() function doesn't cut
it..
unescape("You&# 039;ll never escape!");

Do I have to use regex to replace or is there some other way?

Thanks for any assistance!

var txt = 'apostrophe &#039; / double quote: &#0034; / '
+ ' s: &#115; / è: &#232; / Chinese sign: 新';

txt = txt.replace(/(&#)([0-9]{1,5})(;)/g,
function (a1, a2, a3, a4) {
return String.fromChar Code(a3);
}
);
alert(txt);

Hope this helps,

Or could escape it differently.

If you are using struts you can use StringEscapeUti ls.escapeJavaSc ript.

Would be really nice to have c:out handle that.

Fictitious example:
<c:out escapeJavaScrip t="true" value="You'll never escape!"/>

*g*

How to I unescape this?

Maybe

someVar = someVar.replace (/&lt;/g, "<").replac e(/&gt;/g, ">"
.replace(/&amp;/g, "&");

Using the unescape() function doesn't cut it..
unescape("You&# 039;ll never escape!");

It is not supposed to. unescape() decodes (ASCII) percent-encoded strings.
It was primarily used to decode URI components, and is now deprecated in
favor of decodeURI() and decodeURICompon ent(), which in addition can decode
UTF-8 percent encoding.

Do I have to use regex to replace or is there some other way?

A regular expression like above would not help in your case because the
escaping of `"' needs to take place *before* you insert the value with JSP,
i.e. "on the server".

You do not need `escapeXml="tru e"' if you declare the content of the XHTML
`script' element CDATA, provided the string never contains `"', like
in your example:

<script type="text/javascript">
// <![CDATA[
...
]]>
</script>

But if the `<' and `>' are your only problems, you could as well move the
code to an external script file or simply use HTML instead.
