how to do zebra stripe in xslt - xslt

Question

I'm trying do zebra stripe for my pdf file. The XML like as below:
<root>
<order>
<attribute1>1</attribute1>
<attribute2>2</attribute2>
<attribute3>0</attribute3>
<attribute4>4</attribute4>
<attribute5/>
</order>
</root>
The attribute3 isn't appeared if the value is '0'. Also attribute5 isn't appear if there is no value for it. So I cannot do zebra stripe like as below:
<fo:table-row (colored)>
<fo:table-cell>
<fo:block>
<xsl:text>Attribute1</xsl:text>
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block>
<xsl:text>...</xsl:text>
</fo:block>
</fo:table-cell>
</fo:table-row>
<fo:table-row (non colored)>
<fo:table-cell>
<fo:block>
<xsl:text>Attribute2</xsl:text>
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block>
<xsl:text>...</xsl:text>
</fo:block>
</fo:table-cell>
</fo:table-row>
Because attribute3 and attribute5 is not always appeared in pdf file. How can I do it?

What you need to do here, is first use xsl:apply-templates to select only the child nodes you wish to output (This assumes you are currently positioned on the order element:
<xsl:apply-templates select="*[normalize-space()][. != '0']" />
Then you have a template to match child elements of order elements, like so:
Within this template, you can then output the table-row, and to do the 'coloured' attribute, you can test the 'position' of the current attribute, to see if it is odd or even:
<fo:table-row>
<xsl:if test="position() mod 2 = 0">
<xsl:attribute name="colour">zebra</xsl:attribute>
</xsl:if>
Try this XSLT as a start
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="order">
<fo:table>
<xsl:apply-templates select="*[normalize-space()][. != '0']" />
</fo:table>
</xsl:template>
<xsl:template match="order/*">
<fo:table-row>
<xsl:if test="position() mod 2 = 0">
<xsl:attribute name="colour">zebra</xsl:attribute>
</xsl:if>
<fo:table-cell>
<fo:block>
<xsl:value-of select="local-name()" />
</fo:block>
</fo:table-cell>
<fo:table-cell>
<fo:block>
<xsl:text>...</xsl:text>
</fo:block>
</fo:table-cell>
</fo:table-row>
</xsl:template>
</xsl:stylesheet>
Obviously you would use the correct xsl-fo styling here, and not literally the 'colour=zebra' attribute as shown here....
