Hi,

I have a sequence of nodes - para>graphic>para. I want to associate the graphic element with its previous sibling "para". However, if there is not a graphic element, I don't need select it.

Here is the input:

Code:

<root>
    <para>Data1</para>
    <graphic href="img1.gif"/>
    <para>Data2</para>
    <para>Data3</para>
    <para>Data4</para>
    <graphic href="img4.gif"/>
    <para>Data5</para>
    <graphic href="img5.gif"/>
</root>

Stylesheet:

Code:

<xsl:for-each select="root/para">
            <xsl:value-of select="."/>
            <xsl:text> Image for this para - </xsl:text>
            <xsl:value-of select="following-sibling::graphic[1]/@href"/>
            <xsl:text>            
            </xsl:text>
</xsl:for-each>

Current output:

Code:

Data1 Image for this para - img1.gif
            
Data2 Image for this para - img4.gif
            
Data3 Image for this para - img4.gif
            
Data4 Image for this para - img4.gif
            
Data5 Image for this para - img5.gif

Desired output:

Code:

Data1 Image for this para - img1.gif            

Data4 Image for this para - img4.gif

Data5 Image for this para - img5.gif

Thanks for the help.

I think you want
<xsl:value-of select="following-sibling::*[1][self::graphic]/@href"/>
respectively you want to check e.g.

Code:

<xsl:if test="following-sibling::*[1][self::graphic]">
Image for this para:
  <xsl:value-of select="following-sibling::*[1][self::graphic]/@href"/>
</xsl:if>
