Merge functionality of two xsl files into a single file (not a xsl import or include issue)
- by anuamb
I have two xsl files; both of them perform different tasks on source xml one after another. Now I need a single xsl file which will actually perform both these tasks in single file (its not an issue of xsl import or xsl include):
say my source xml is:
<LIST_R7P1_1
<R7P1_1
<LVL2
<ORIG_EXP_PRE_CONV#+#
<EXP_AFT_CONVabc
<GUARANTEE_AMOUNT#+#
<CREDIT_DER/
</LVL2
<LVL21
<AZ#+#
<BZbz1
<AZaz2
<BZ#+#
<CZ/
</LVL21
</R7P1_1
</LIST_R7P1_1
My first xsl (tr1.xsl) removes all nodes whose value is blank or null:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node()">
<xsl:if test=". != '' or ./@* != ''">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:if>
<xsl:template
</xsl:stylesheet
The output here is
<LIST_R7P1_1
<R7P1_1
<LVL2
<ORIG_EXP_PRE_CONV#+#
<EXP_AFT_CONVabc
<GUARANTEE_AMOUNT#+#
</LVL2
<LVL21
<AZ#+#
<BZbz1
<AZaz2
<BZ#+#
</LVL21
</R7P1_1
</LIST_R7P1_1
And my second xsl (tr2.xsl) does a global replace (of #+# with text blank'') on the output of first xsl:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0"
<xsl:template name="globalReplace"
<xsl:param name="outputString"/
<xsl:param name="target"/
<xsl:param name="replacement"/
<xsl:choose
<xsl:when test="contains($outputString,$target)">
<xsl:value-of select=
"concat(substring-before($outputString,$target),
$replacement)"/>
<xsl:call-template name="globalReplace">
<xsl:with-param name="outputString"
select="substring-after($outputString,$target)"/>
<xsl:with-param name="target" select="$target"/>
<xsl:with-param name="replacement"
select="$replacement"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$outputString"/>
</xsl:otherwise>
</xsl:choose
</xsl:template
<xsl:template match="text()"
<xsl:template match="@*|*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet
So my final output is
<LIST_R7P1_1
<R7P1_1
<LVL2
<ORIG_EXP_PRE_CONV
<EXP_AFT_CONVabc
<GUARANTEE_AMOUNT
</LVL2
<LVL21
<AZ
<BZbz1
<AZaz2
<BZ
</LVL21
</R7P1_1
</LIST_R7P1_1
My concern is that instead of these two xsl (tr1.xsl and tr2.xsl) I only need a single xsl (tr.xsl) which gives me final output?
Say when I combine these two as
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
<xsl:template match="@*|node()"
<xsl:if test=". != '' or ./@* != ''">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:if>
<xsl:template name="globalReplace"
<xsl:param name="outputString"/
<xsl:param name="target"/
<xsl:param name="replacement"/
<xsl:choose
<xsl:when test="contains($outputString,$target)">
<xsl:value-of select=
"concat(substring-before($outputString,$target),
$replacement)"/>
<xsl:call-template name="globalReplace">
<xsl:with-param name="outputString"
select="substring-after($outputString,$target)"/>
<xsl:with-param name="target" select="$target"/>
<xsl:with-param name="replacement"
select="$replacement"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$outputString"/>
</xsl:otherwise>
</xsl:choose
</xsl:template
<xsl:template match="text()"
<xsl:call-template name="globalReplace"
<xsl:with-param name="outputString" select="."/
<xsl:with-param name="target" select="'#+#'"/
<xsl:with-param name="replacement" select="''"/
</xsl:call-template
</xsl:template
<xsl:template match="@|"
<xsl:copy
<xsl:apply-templates select="@*|node()"/
</xsl:copy
</xsl:template
</xsl:stylesheet
it outputs:
<LIST_R7P1_1
<R7P1_1
<LVL2
<ORIG_EXP_PRE_CONV
<EXP_AFT_CONVabc
<GUARANTEE_AMOUNT
<CREDIT_DER/
</LVL2
<LVL21
<AZ
<BZbz1
<AZaz2
<BZ
<CZ/
</LVL21
</R7P1_1
</LIST_R7P1_1
Only replacement is performed but not null/blank node removal.
