IIUC, you want to lookup many entries based on data in the XML.  You
have not mentioned what handles the lookup.  If you use the
SQLTransformer, the second transformation adds several
sql:execute-query elements.  The third transformation calls the
SQLTransformer.  A fourth transformation may be needed to format the
results of the the third transformation if they do not insert the
desired HTML.

This is a straight pipeline.  No transformation inserts data from
another pipeline; each just inserts the information needed for the
next step.
