 The whitespace in your output is a copy of the inter-element whitespace from your input, so your simplest solution is to remove it from the input using <xsl:strip-space elements="seg"/> The alternative would be to do something like <xsl:apply-templates select="text()[normalize-space()]"/> Regards, Michael Kay http://www.saxonica.com/ http://twitter.com/michaelhkay > -----Original Message----- > From: Manuel Souto Pico [mailto:manuel.souto@xxxxxxxxxxxxxx] > Sent: 25 August 2009 10:11 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: generate an element only if the result is not empty > > Hello! > > Again I have a doubt with generating empty elements.
