Subject: Re: [xsl] the fastest way to test if variable is empty From: Dusan Zatkovsky <zatkovsky@xxxxxxxxxxxx> Date: Thu, 9 Dec 2004 09:32:48 +0100 |
Ok, here is example structure of code and why I use it: At first, my old implementation does something like: <xsl:variable name="mayContinue"> <xsl:choose> <xsl:when test="some_big_test_over_big_xml_trees_which_was_very_slow">1</xsl:when> <xsl:otherwise>0</xsl:otherwise> </xsl:choose> <xsl:if test="$mayContinue=1"> <xsl:if test="other_big_test_to_check_if_something_will_be_processed"> <!-- print header --> <!-- process data and generate output --> <!-- print bottom --> </xsl:if> </xsl:if> but test other_big_test_to_check_if_something_will_be_processed was very slow. Much faster it is like this: ..... <xsl:if test="$mayContinue=1"> <xsl:variable name="processOutput"> <!-- process data and generate output --> </xsl:variable> <xsl:if test="string-length($processOutput)!=0"> <!-- print header --> <xsl:value-of select="$processOutput"/> <!-- print bottom --> </xsl:if> </xsl:if> But I am afraid that when $processOutput will be too big (for example 100000 lines of text output), test for it's string-length may be slow. I will test it. Thanks -- S pozdravom, Dusan Zatkovsky
