Subject: RE: [xsl] How to test if a named attribute exists and put the name of that attribute in an generic way From: "Braumüller, Hans" <H.Braumueller@xxxxxxxxxxxx> Date: Mon, 7 Apr 2003 16:00:19 +0200 |
OK, excuse, its seems i am with my brain on other place than here. Peace, Hans Braumüller Believe in Progress http://ausbeutung.com > Is empty equal to not exist? No a="" is an existing attribute node with string value empty. If you want to copy attribute a if it exists and do nothing otherwise, that's <xsl:copy-of select="@a"/> If you only want to copy a if its value is non empty then that is <xsl:copy-of select="@a[. != '']"/> [. != ''] is, as you say, the same as [string(.) != ''] it is also the same as [string(.)] as in a boolean predicate the string will be taken as true if it is non empty and false if it is empty.
