Re: [xsl] Transform selected attribute to element when element already has a value | XSLT 2.0

Hi, Martin:

B B B B B B B B B B B  The purposesof flattening the XML are:

1.B B B B After the $keepAttr is flattened to element (therewill not be any
attribute ), I can further transform the flattened XML to JSON.That is the
purpose of this post:

https://stackoverflow.com/questions/67145900/xquery-constructs-string-object-
with-sequential-ancestor-node-names
The original <businessCenters> will be transformed to JSON array.
B B B B B B B B B B B B B B B B B  <calculationPeriodDatesAdjustments>
B B B B B B B B B B B B B B B B B B B 
<businessDayConvention>PRECEDING</businessDayConvention>
B B B B B B B B B B B B B B B B B B B  <businessCenters id="businessCenters">
B B B B B B B B B B B B B B B B B B B B B 
<businessCenter>USNY</businessCenter>
B B B B B B B B B B B B B B B B B B B B B 
<businessCenter>GBLO</businessCenter>
B B B B B B B B B B B B B B B B B B B  </businessCenters>
B B B B B B B B B B B B B B B B B  </calculationPeriodDatesAdjustments>

B 
It is legitimate to transform id as child element of <businessCenters>. But
data transformation is not just for convenience,if I transform that id out of
<businessCenters> as a sibling of <businessDayConvention>. B The context of
idB  is completed lost. In asearch engine, index broot/businessCenters/idb
vs broot/idb returns differentvalue.B

What is the criteria to transform an attribute to a child element of its
parent as is done for the "id" of the "bcs" element and what is the
criteria for the other choice, to not include the new element as a child
but to make it a sibling of the (previous) parent element?
