Subject: Re: [xsl] accessing previously created element From: Greg Faron <gfaron@xxxxxxxxxxxxxxxxxx> Date: Wed, 01 May 2002 13:52:55 -0600 |
unfortunately when transforming the i'th 'a' element to a 'b' (assume i > 1) I also need to access the (i-1)'th 'b' element; that is, the values used to create a 'b' element are dependent upon the current 'a' element being transformed and the preceding 'b' element. Is this possible? in a single pass?
<xsl:template name="b-from-a"> <xsl:param name="local-a" /> <xsl:choose> <xsl:when test="not($local-a)"> <!-- Shouldn't be reached unless your initial call is bogus. --> </xsl:when> <xsl:when test="$local-a/preceding-sibling::a[1]"> <xsl:variable name="prev-b"> <xsl:call-template name="b-from-a"> <xsl:with-param select="$local-a/preceding-sibling::a[1]" /> </xsl:call-template> </xsl:variable> <!-- Use $local-a and $prev-b to construct "b" --> <xsl:value-of select="..." /> </xsl:when> <xsl:otherwise> <!-- First occurrence (i == 1) Construct it however you normally do it. --> <xsl:value-of select="..." /> </xsl:otherwise> </xsl:choose> </xsl:template>
