B1if http calls within xsl:for-each

Hi,

my scenario description:

1. make a sql call to b1 and retrieve a table object with multiple rows.

2. make an http call for each row

3. each http call connects with 3rd party API and sends 1 sms for each row.

To achieve this I make xsl:for-each to the rows and set <call></call> with appropriate properties inside.

The xml result seems ok as xml shows calls to each rows, but the problem is that I am receiving SMS for only first row.

So this seems like I can't make multiple http calls within xsl:for-each. How can I solve this problem?

form for calling http:

as you can see the http calls are set for each row correctly. But In reality only first http call is made. How do I solve this?

Hi there,

I don't think that you can pass multiple call objects to one HTTP Call atom. You can use graphical for-each atom instead to achieve your goal. Just split the result by your for-each statement and place the HTTP Call inside the for-each block.

Thanks! That worked.

Now I have another problem. I need polish characters in side the <query></query> of http call. The result XML shows correctly, but when I receive SMS all the polish characters are broken. I have already set in SMS service providers api to use UTF-8, so maybe there's something I could do in integration framework to correct this?
