HTTP Receiver -> Response message

[Former Member]

Hi,

I have a HTTP Receiver scenario. I get the data from a Webservice and sent the data with a HTTP Request to our customer. So far we have no problem. Our customer is returning a payload structure like the one below.

Now the problem here is, there is a <start>, <end> tag and "0" and "OK" before and after the XML structure as you can see below. How can I parse these type of messages?

<start>

0

OK

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE AMS_XML_DATA SYSTEM "Group1.dtd"><AMS_XML_DATA><Header><ErrorCode>0</ErrorCode><ErrorMessage>OK</ErrorMessage><Version>1.0</Version><SourceId>XXX</SourceId><MessageId>XXX99998888777766665555</MessageId></Header><Segment><IgnoreFg></IgnoreFg><ErrorCode>555</ErrorCode><ErrorMessage>PR DA FO</ErrorMessage><TransactionType>N</TransactionType><TransactionId>XXX99998888777766665555</TransactionId></Segment></AMS_XML_DATA>

<end>

Thank you in advance.

Best Regards,

Arman

use a java mapping. Extract the substring which contains the XML only and then initiate a parser.

Hi,

Use prolog and epilog concepts. For more details about prolog and epilog concept see the below link.

I think to parse this message is impossible, because it's not well formed.

<start>

0

OK

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE AMS_XML_DATA SYSTEM "Group1.dtd"><AMS_XML_DATA><Header><ErrorCode>0</ErrorCode><ErrorMessage>OK</ErrorMessage><Version>1.0</Version><SourceId>XXX</SourceId><MessageId>XXX99998888777766665555</MessageId></Header><Segment><IgnoreFg></IgnoreFg><ErrorCode>555</ErrorCode><ErrorMessage>PR DA FO</ErrorMessage><TransactionType>N</TransactionType><TransactionId>XXX99998888777766665555</TransactionId></Segment></AMS_XML_DATA>

<end>

A declaration of DOCTYPE outside the header / prolog is not allowed.

Aditionally the start and end tags are not closed. So the basic question is, why does the sender transfers a not well formed XML?

thats exactly where a java mapping can help since the incoming payload for the mapping is always treated as an inputsream

Yes - you are right with that ;o)
