Subject: Re: [xsl] current context preceding-sibling then following-sibling From: David Carlisle <davidc@xxxxxxxxx> Date: Tue, 8 Mar 2005 22:33:58 GMT |
/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 context on the right of the = is the same as that on the left, namely the field node, which is why the @id to the left of the = selects id attributes of field. so /data/animals/animal[@id = /data/code/record[field[@id = ( preceding-sibling::animal[1]/@id ) ]]/@id] will always compare @id to the empty set as the field element has no sibling element called animal. Too late to really check, but I suspect that you can't do this with a single xpath if you don't allow yourself any variables or the current() function (eg as provided by xslt).
