This Might Be All You Really Want

DRxml2arrays.js

There’s all the javascript required to parse a Dungeon Runners’ XML file into javascript arrays.

I love that of the char viewers I know of, they're all done a different way. Demos uses XLS, You've got Javascript, I'm in php, and there's an ASP one floating around as well.

/me thinks we need a community page with explanations of how it works and basic examples for each language.

Nice work. What would be cool is if the DR devs would provide an alternate output in json. It sure would make consuming the data easier than parsing xml.

<script type="text/javascript">
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
function loadXML(xmlFile) {
xmlDoc.async="false";
xmlDoc.onreadystatechange=verify;
xmlDoc.load(xmlFile);
ticker=xmlDoc.documentElement;
DRxml2arrays( xmlDoc )
}
function verify() {
return (xmlDoc.readyState == 4)
}
}
