Subject: Re: [xsl] xsl:for - Only for existing nodes, how? From: David Carlisle <davidc@xxxxxxxxx> Date: Tue, 21 Feb 2006 17:37:11 GMT |
> This was just an example and my real xml > file goes much deeper after "control". if the expressions in the test are more complex it may help to stick them in a variable. <xsl:for-each select="/tree/controls/control"> <xsl:variable name="i1" select="ho/hum/ha"/> <xsl:variable name="i2" select="fee/fi/fo/fum"/> <xsl:if test="$i1 and $i2"> <xsl:value-of select="$i1"/> <xsl:value-of select="$i2"/> </xsl:if> </xsl:for-each> that way you don't have to repeat the expression both in the test and the value of. On the other hand it may make no difference as your xslt engine may spot repeated sub-expressions and effectively make them into implicit internal variables anyway.
