Can I test that example in the sandbox. Of course, I will have to write a pipeline to access eXist?

Hi Ilango,
I don't know if this is the best practice, only that when it
worked I was really impressed.
The data is already in eXist. It is simply that it was made
from sql and so it has relationships like that. One of them
is that a 'station' has one to many with 'channel' so the path
//channels[sta='WLA']
returns a many nodes. I want to list the stations, then when
they are checked/unchecked, expand/shrink the list.
Something like this:
--Hank
<xforms:instance id="sites"
src=" http://example.org/exist/rest/db/sites.xml"/><xforms:instance id="chans"
src=" http://example.org/exist/rest/db/chans.xml"/><xforms:instance id="all-select"> <select xmlns=""> <stas/> <sta-seq/> </select> </xforms:instance>
<xforms:bind nodeset="instance('all-select')"> <xforms:bind nodeset="sta-seq" calculate="string-join(tokenize(../
stas,'\s'),',')"/> </xforms:bind> <xforms:group ref="instance('sites')"> <xforms:repeat nodeset="/sites/site" id="sites-repeat"> <xxforms:variable name="sta" select="sta"/> <xforms:select ref="instance('all-select')/stas" appearance="full"> <xforms:choices> <xforms:item> <xforms:value><xforms:output value="$sta"/></xforms:value> <xforms:label><xforms:output value="$sta"/></xforms:label> </xforms:item> </xforms:choices> </xforms:select> </xforms:repeat> </xforms:group> <xforms:group ref="instance('chans')"> <xforms:variable name="sta-seq" select="instance('all-select')/sta-
