XSLT Row counter excluding Null and Zero - xslt

Question

<Rows>
<Row RowNo="1" Amount="0,0"/>
<Row RowNo="2" Amount="12"/>
<Row RowNo="3" Amount=""/>
<Row RowNo="4" Amount="00"/>
<Row RowNo="5" Amount="33"/>
<Row RowNo="6" Amount="0,00"/>
<Row RowNo="7" Amount="0"/>
<Row RowNo="8" Amount="00,2"/>
</Rows>
These Row's are my input. I want the output to exclude rows where #Amount is '' or 0. And also not count the row for when #Amount = '' and = 0.
Expected result:
<Rows>
<Row RowNo="1" Amount="12"/>
<Row RowNo="2" Amount="33"/>
<Row RowNo="3" Amount="00,2"/>
</Rows>
How can I do this?

Answer 1

With your given input, a specific (based on input) solution in XSLT 1.0 can be as following:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<Rows>
<xsl:for-each select="Rows/Row">
<xsl:choose>
<xsl:when test="#Amount != '' and (number(#Amount) * 1) != '0' and translate(#Amount, '0', '') != ','">
<xsl:copy>
<xsl:attribute name="RowNo">
<xsl:value-of select="count(preceding-sibling::*[#Amount != '' and (number(#Amount) * 1) != '0' and translate(#Amount, '0', '') != ',']) + 1" />
</xsl:attribute>
<xsl:for-each select="#*">
<xsl:if test="name() != 'RowNo'">
<xsl:attribute name="{name()}"><xsl:value-of select="." /></xsl:attribute>
</xsl:if>
</xsl:for-each>
<xsl:apply-templates select="node()" />
</xsl:copy>
</xsl:when>
</xsl:choose>
</xsl:for-each>
</Rows>
</xsl:template>

How about something simple, for a change?
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/Rows">
<xsl:copy>
<xsl:for-each select="Row[translate(#Amount, ',0', '')]">
<Row RowNo="{position()}" Amount="{#Amount}"/>
</xsl:for-each>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
