Hi guys,

let's say I have a XML file attached.

I'd like to display in the report a list of persons displaying name and titles. That's something what I was able to do, but then I want to display a contacts that are in 1 to N relationship to that person and I found it as a problem. Can you please help?

In general I do not know how to relate email to the current person.
Report is attached.

Thanks a lot for the hint ...

To get the emails all within your dataSet, you would need to make the <email> node your row mapping. This would allow you to grab each email and the appropriate contact info. However, only the first phone number will be grabbed. So, you'd likely need at least two dataSets because of how the XML is laid out.

Here's a way to do it with your XML as attached. A second dataSet is used to grab the person's first and last names and their associated phone numbers. This table is then embedded in the group footer and filtered to show all phone numbers for the given contact.

Super ! works like a charm ... Thanks a lot

now back to my question ... What is the best practice for creating XML's that fit the BIRT design?

Or is it ok to design all XML/reports as this one ?

Thanks

I don't know if I'm the best person to say the ideal XML setup Smile

, but if you were to do something like the attached XML file, you could use a single dataSet, which can be found in the updated report design. With lots of data, the single dataSet should be faster because you don't have to use a filter.
