Make your XML look pretty

Credit goes to Joe Rinehart for most of this from this post.
ColdFusion ships with JDom which gives you full access to the JDom API. Many of the applications I work with have some kind of XML component to them and sometimes the XML is difficult to read if it’s not formatted nicely.
I’ve used Joe’s code example to create a simple interface on top of it. It also works with valid XHTML.
<cfparam name="form.submit" default=""/>
<cfparam name="form.xml" default=""/>
<cfscript>
function prettyXML(xmlString){
var fileObj = "";
var builder = "";
var format = "";
var out = "";
var document = "";
var fileInStream = "";
var fileOutStream = "";
var filePath = expandPath("./prettyXML.xml");
try{
fileWrite(filePath, arguments.xmlString);
fileObj = createObject("java", "java.io.File").init(filePath) ;
builder = createObject("java", "org.jdom.input.SAXBuilder").init() ;
format = createObject("java", "org.jdom.output.Format").getPrettyFormat() ;
format.setIndent(" ");
out = createObject("java", "org.jdom.output.XMLOutputter").init(format);
fileInStream = createObject("java", "java.io.FileInputStream").init(fileObj );
document = builder.build(fileInStream);
fileInStream.close();
fileDelete(filePath);
return out.outputString(document);
}
catch(Any excpt){
if(isDefined("fileInStream") and fileInStream neq ""){
fileInStream.close();
}
writeOutput("<p>#excpt.message#</p>");
writeOutput("<p>#excpt.stacktrace#</p>");
}
}
</cfscript>
<html>
<head>
<title>Paste your ugly XML</title>
<style type="text/css">
body, input{
font-family:Trebuchet MS;
}
</style>
</head>
<body>
<h3>Input your XML:</h3>
<cfoutput>
<form action="#cgi.SCRIPT_NAME#" method="post">
<p><textarea name="xml" rows="20" cols="100">#form.xml#</textarea></p>
<input name="submit" type="submit" value="Go"/>
</form>
<h3>Pretty XML</h3>
<cfif len(form.submit) and len(form.xml)>#htmlCodeFormat(prettyXML(form.xml))#</cfif>
</cfoutput>
</body>
</html>
