I need to list all the INST names but only if the "onlyTesters" node don´t exists in the "inst/idef" part of XML body above.
I know thats strange but I can´t change the XML I receive.
XML:
<river>
<station num="699">
<inst name="FLU(m)" num="1">
<idef></idef>
</inst>
<inst name="Battery(V)" num="18">
<idef>
<onlyTesters/>
</idef>
</inst>
</station>
<INST name="PLU(mm)" num="0" hasData="1" virtual="0"/>
<INST name="FLU(m)" num="1" hasData="1" virtual="0"/>
<INST name="Q(m3/s)" num="3" hasData="1" virtual="1"/>
<INST name="Battery(V)" num="18" hasData="1" virtual="0"/>
</river>
XSL:
<xsl:template match="/">
<xsl:apply-templates select="//INST[@hasData = 1 and not(//inst[@num=(current()/@num)]/idef/onlyTesters)]/@name"/>
</xsl:template>
<xsl:template match="//INST[@hasData = 1 and not(//inst[@num=(current()/@num)]/idef/onlyTesters)]/@name">
<xsl:value-of select="@name"/>,
</xsl:template>
I´m having no match.
This is the result I expect:
PLU(mm),FLU(m),Q(m3/s)
You can achieve this with only one template:
<xsl:template match="/">
<xsl:for-each select="//INST[@hasData='1' and not(@name=//inst[idef/onlyTesters]/@name)]">
<xsl:value-of select="@name"/>
<xsl:if test="position() != last()">, </xsl:if>
</xsl:for-each>
</xsl:template>
Output is:
PLU(mm), FLU(m), Q(m3/s)
Cross-references are best resolved using a key - for example:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="UTF-8" />
<xsl:key name="inst" match="inst" use="@name" />
<xsl:template match="/river">
<xsl:for-each select="INST[@hasData = 1 and not(key('inst', @name)/idef/onlyTesters)]">
<xsl:value-of select="@name"/>
<xsl:if test="position() != last()">,</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Or even simpler:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="UTF-8" />
<xsl:key name="exclude" match="onlyTesters" use="ancestor::inst/@name" />
<xsl:template match="/river">
<xsl:for-each select="INST[@hasData = 1 and not(key('exclude', @name))]">
<xsl:value-of select="@name"/>
<xsl:if test="position() != last()">, </xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
