You can't, because the source you provided is not
well-formed XML. So unless you write your own parser that
would transform this proprietary document into XML DOM that
your XSLT would grok, it's simply impossible.

Even if you write your own parser, I'm not really certain
how did you get to '4/56' as content for the second
ChildElement element in your resulting document.

Now, if you were using well-formed XML, I suppose you could
do something like this:

<xsl:styleshe et version="1.0"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node( )">
<xsl:copy>
<xsl:apply-templates select="@*|node ()"/>
</xsl:copy>
</xsl:template>
<xsl:template
match="Value[not(preceding-sibling::Value)]">
<xsl:apply-templates select="text()"/>
<xsl:apply-templates
select="followi ng-sibling::*[self::Value]"
mode="append"/>
</xsl:template>
<xsl:template match="Value[preceding-sibling::Value]"/>
<xsl:template match="*" mode="append">
<xsl:text>/</xsl:text>
<xsl:apply-templates select="text()"/>
</xsl:template>
</xsl:stylesheet>

(Hint: posting sloppy examples is not a very good idea if
you're asking for help.)

Re: How to Concat in XSLT

As XSLT 2.0 has just been released a couple of days ago, here it an
XSLT 2.0 solution. To concatenate all the values separated with slashes
it just needs
<xsl:value-of select="Value" separator="/"/>

<xsl:styleshe et version="2.0"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform">
<xsl:template match="@*|node( )">
<xsl:copy>
<xsl:apply-templates select="@*|node ()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ChildEle ment">
<xsl:copy>
<xsl:value-of select="Value" separator="/"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

George

Re: How to Concat in XSLT

Pavel Lepin,

Thanks for your reply, this is exactly what I wanted and sorry for my
bad source example I usually don't post such bad examples.

Your code worked well with my example but I didn't know how to
integrate it with my already existent XLST code, so I had to perform
two transformations for both using both XSLT, so to solve this I need
to understand your XSLT, is there any good reference you know that can
help me to understand this XSLT code?

Also if you can explain even if a little of it then it will be great.

Thanks anyway,
Zaid H. Safadi

Re: How to Concat in XSLT

George,

Thanks for your reply, I'm using the .NET Framework 1.1 engine for XSLT
transformation so i don't think it support XSLT 2.0, I'm already
planning to convert my work to .NET 2.0 so maybe i can make use of the
new features of XSLT 2.0

Thanks,
Zaid H. Safadi

Both System.Xml.Xsl. XslTransform in .NET 1.x and
System.Xml.Xsl. XslCompiledTran sform in .NET 2.0 support XSLT 1.0.
If you want to use XSLT 2.0 with .NET then you need Saxon from
<http://www.saxonica.co m/>.

Re: How to Concat in XSLT

For basic educational material on XML and XSLT, I usually point folks to
the many articles/references at http://www.ibm.com/xml

For specific "how do I" questions about XSLT, always check whether what
you need is available as one of the examples at

http://www.dpawson.co.uk/xsl/sect2/sect21.html

It sounds like you're at a point where both of those resources will be
hugely useful to you.

That's not XML. Assuming you just mistyped it and that the ChildElements
do actually have start-tags and end-tags, and that you also missed a
slash in the "4/5/6" output, then there are two ways:

1. Concatenation using a recursive named template:

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
version="1.0">

<xsl:output method="xml" indent="yes"/>

<xsl:template match="Root">
<Root>
<xsl:apply-templates/>
</Root>
</xsl:template>

<xsl:template match="ParentEl ementX">
<ParentElementX >
<xsl:apply-templates/>
</ParentElementX>
</xsl:template>

<xsl:template match="ChildEle ment">
<ChildElement >
<xsl:call-template name="join-with-slashes">
<xsl:with-param name="children" select="Value"/>
</xsl:call-template>
</ChildElement>
</xsl:template>

<xsl:template name="join-with-slashes">
<xsl:param name="children"/>
<xsl:param name="counter">
<xsl:text>1</xsl:text>
</xsl:param>
<xsl:choose>
<xsl:when test="$counter> =count($childre n)">
<xsl:text>/</xsl:text>
<xsl:value-of select="$childr en[$counter]"/>
</xsl:when>
<xsl:otherwis e>
<xsl:if test="$counter> 1">
<xsl:text>/</xsl:text>
</xsl:if>
<xsl:value-of select="$childr en[$counter]"/>
<xsl:call-template name="join-with-slashes">
<xsl:with-param name="children" select="$childr en"/>
<xsl:with-param name="counter" select="$counte r+1"/>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

</xsl:stylesheet>

2. Concatenation using normal templates (much faster):

<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
version="1.0">

<xsl:output method="xml" indent="yes"/>
<xsl:strip-space elements="Child Element"/>

<xsl:template match="Root">
<Root>
<xsl:apply-templates/>
</Root>
</xsl:template>

<xsl:template match="ParentEl ementX">
<ParentElementX >
<xsl:apply-templates/>
</ParentElementX>
</xsl:template>

<xsl:template match="ChildEle ment">
<ChildElement >
<xsl:apply-templates/>
</ChildElement>
</xsl:template>

<xsl:template match="Value">
<xsl:value-of select="."/>
<xsl:if test="position( )!=last()">
<xsl:text>/</xsl:text>
</xsl:if>
</xsl:template>

</xsl:stylesheet>

Re: How to Concat in XSLT

Thank you so much guys,

Yes my source example was bad and I meant to add en end tag for each
ChildElement and I forgot to include the slash to output 4/5/6.

But I read a book about XML, Xpath, Schema and XSLT "Addison Wesley -
Essential Xml Reference - Xpath, Xslt, Soap.pdf" and it's great, I am
able to understand your examples now and it worked with me and solved
my problems, so really thanks for all contributors.

Thanks,
Zaid H. Safadi
