Spry XML Grouping

Question

I am using PHP to query my database and then export as XML
for Spry to read.
FYI: Addresses and Defendants are normalized and linked using
unique ID's.
I am trying to group all of serviceDefendants for each
address on the html page. For instance
Address1:
Defendant 1
Defendant 2
Address 2:
Defendant 3
Defendant 2 (One defendant can have multiple addresses)
That is how I am trying to display..however, I cannot figure
out how to get Spry to group. I am using spry:repeatchildren. I'm
thinking the architecture of the XML needs to change, in which case
I'm in the wrong forums...but if anybody does know how the arch.
should look, that would be helpful.
Right now Spry is repeating the address and the defendant
regardless.

Answer 1

NestedXMLDataSet is the way to go. The architecture will
depend largely on the output XML that is generated by your
database. How many levels of data are you dealing with? Is it
something simple like:
<address id="123">
<resident id="001">Defendant 1</resident>
<resident id="002">Defendant 2</resident>
</address>
Or is the database XML output more complex, with more nested
structure:
<addresses>
<address id="123">
<streetnumber>1234</streetnumber>
<streetname>Main Street</streetname>
<city>Anywhere</city>
<state>US</state>
<zipcode>12345</zipcode>
<residents>
<resident id="001">
<firstname>firstName</firstname>
<lastname>lastName</lastname>
</resident>
<resident id="001">
<firstname>firstName</firstname>
<lastname>lastName</lastname>
</resident>
</residents>
</address>
</addresses>
The XML structure is going to determine what the vars are for
using/accessing the data with Spry.Data.nestedXMLDataSet and. to
some extent, also when/where you would need to use repeat vs.
repeatchildren. Can you provide a sample of the XML structure with
dummy values?
