Re: current context preceding-sibling then following-

animal sibling name
Unforturnately, stuck with single XPATH queries... so, here is what I
have come up with... I feel like I am really really close:

/data/animals/animal[@id = /data/code/record[field[@id = ( '60' ) ]]/@id]


The above '60' is in correct context of /data/animals/animal (it is
the value of id).. do I lose context on the right hand side of this
equation?  The following substition for '60' does not work
preceding-sibling::animal[1]/@id... so:

/data/animals/animal[@id = /data/code/record[field[@id = (
preceding-sibling::animal[1]/@id  ) ]]/@id]
