Cool, glad you found it in the docs. Don't be put off by the other guys' requests to post a link and read the posting guidelines. In general they are quite right, of course. In this case, though, posting a link to a map wouldn't have helped with the immediate problem of the XML simply not validating.
You mentioned that you still have a problem in IE. But now that your XML is valid, IE does seem to parse it OK. Open this URL directly in IE: http://209.62.63.202/locations/phpsqlsearch_genxml.php?lat=33.7489954&lng=-84.3879824&radius=1 I see this result in IE8: <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE markers* (View Source for full doctype...)*> <markers /> This indicates that the XML document did parse successfully. (Note the comment about the doctype, and the <markers />.) So if you're still having trouble in IE, it may not be an XML problem per se - it may well be related to the JavaScript API. This may be the point at which posting that map link will prove helpful... :-) But first a more global question: It sounds like you are generating this XML on your server and consuming it in your JavaScript code, right? Why are you using XML at all? JSON would be much simpler to work with in your JavaScript code. -Mike On Wed, Mar 31, 2010 at 11:09 AM, Jerry Garciuh <[email protected]>wrote: > Thank you very much Mike.
