I want to split an address on semicolons (;
) into rows separated by <br />
:
e.g. if address
=123 Elm Street
, I want to output 123 Elm Street
,
but if address
=123 Elm Street;PO Box 222
, I want to output
123 Elm Street<br />PO Box 222
and if address
=123 Elm Street;PO Box 222;c/o James Jones
, I want to output
123 Elm Street<br />PO Box 222<br />c/o James Jones
Is there a way to do this? (probably easy but I'm not that familiar with XSLT)
The plain XSL selector is
<xsl:value-of select="address"/>
and I would like to modify this XSLT fragment to split on semicolon.
update: Apparently the answer involves the use of <xsl:call-template>
and the functions substring-before()
and substring-after()
.
But I'm a beginner to XSLT and I could really use some help for how to do this.
I. Plain XSLT 1.0 solution:
This transformation:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="text()" name="split">
<xsl:param name="pText" select="."/>
<xsl:if test="string-length($pText)">
<xsl:if test="not($pText=.)">
<br />
</xsl:if>
<xsl:value-of select=
"substring-before(concat($pText,';'),';')"/>
<xsl:call-template name="split">
<xsl:with-param name="pText" select=
"substring-after($pText, ';')"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
when applied on this XML document:
<t>123 Elm Street;PO Box 222;c/o James Jones</t>
produces the wanted, corrected result:
123 Elm Street<br />PO Box 222<br />c/o James Jones
II. FXSL 1 (for XSLT 1.0):
Here we just use the FXSL template str-map
(and do not have to write recursive template for the 999th time):
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:testmap="testmap"
exclude-result-prefixes="xsl f testmap"
>
<xsl:import href="str-dvc-map.xsl"/>
<testmap:testmap/>
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:variable name="vTestMap" select="document('')/*/testmap:*[1]"/>
<xsl:call-template name="str-map">
<xsl:with-param name="pFun" select="$vTestMap"/>
<xsl:with-param name="pStr" select=
"'123 Elm Street;PO Box 222;c/o James Jones'"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="replace" mode="f:FXSL"
match="*[namespace-uri() = 'testmap']">
<xsl:param name="arg1"/>
<xsl:choose>
<xsl:when test="not($arg1=';')">
<xsl:value-of select="$arg1"/>
</xsl:when>
<xsl:otherwise><br /></xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
when this transformation is applied on any XML document (not used), the same, wanted correct result is produced:
123 Elm Street<br/>PO Box 222<br/>c/o James Jones
III. Using XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="text()">
<xsl:for-each select="tokenize(.,';')">
<xsl:sequence select="."/>
<xsl:if test="not(position() eq last())"><br /></xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
when this transformation is applied on this XML document:
<t>123 Elm Street;PO Box 222;c/o James Jones</t>
the wanted, correct result is produced:
123 Elm Street<br />PO Box 222<br />c/o James Jones
