Hi Guys,

I have a Ruby API that is getting called by a Flex app using POST. The  
problem is as long as data is in the format of -

user[name]=alsk  
user[email]=klsd  
user[pass]=03493

it is fine. But, when it has say two root elements like,

user[name]=alsk  
user[email]=klsd  
user[pass]=03493  
fc\_id =232

It will start crapping out with error messages like -  
Session ID: e3fe6e12eb9f685d82d87f413590efa9  
Parameters: {“format”=\>#\<Mime::Type:0xb797b21c @synonyms=[“text/xml”,  
“application/x-xml”], @symbol=:xml, @string=“application/xml”\>,  
“exception”=\>"#\<REXML::ParseException: malformed XML: missing tag  
start\nLine: \nPosition: \nLast 80 unconsumed characters:\n\<user[email]\>  
removed\_email\_address@domain.invalid\</user[email]\>\<user[first\_name]\>nuwan\</user[first\_nam\>\n/usr/local/lib/ruby/1.8/rexml/parsers/baseparser.rb:346:in

What is the problem? Can I only pass 1 record with a set of values or  
can I  
pass two records. Same thing works for GET.

Please advise.

## Thx,

The error message is about malformed XML. Maybe you could look at the  
xml source to see what’s wrong.  
For example - there’s \</user[first\_nam\> tag that seems wrong.

Other than that, it would help if you specify what framework are you  
using (rails, active webservice, etc.)

- this doesn’t look like a plain POST request since XML somehow got  
into processing…
