Re: [xsl] Is the first preceding-sibling a processing-instruction?

["Imsieke, Gerrit, le-tex gerrit.imsieke@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Hi Rick,

1) You are looking for elements that are simultaneously processing 
instructions. You need to replace * with node().

2) The immediately preceding sibling might be a whitespace-only text node.

Try this (untested):

preceding-sibling::node()[empty(self::text()[not(normalize-space())])][1][self::processing-instruction()]
