xslt loop on a semicolon seperated list

I will have a value that is a semi colon delimited string.
<xsl:value-of select="@Keyword"/>

keyword1;keyword2;keyword3

I want something in my xslt that will look and create list items out of the values that are seperated by semi-colons.

So
keyword1;keyword2;keyword3

Would be
<ul>
  <li>keyword1</li>
  <li>keyword2</li>
  <li>keyword3</li>
</ul>

Thanks

you will need some recursive processing in XSLT1
<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

    xmlns:xd="http://www.oxygenxml.com/ns/doc/xsl" version="1.0">

    <xsl:variable name="keyword">keyword1;keyword2;keyword3</xsl:variable>

    <xsl:template match="/">

        <ul>

            <xsl:call-template name="splitter">

                <xsl:with-param name="str" select="$keyword"/>

                <xsl:with-param name="sep" select="';'"/>

            </xsl:call-template>

        </ul>

    </xsl:template>

<xsl:template name="splitter">

    <xsl:param name="str"/>

    <xsl:param name="sep"/>

    <xsl:choose>

        <xsl:when test="contains($str, $sep)">

            <li><xsl:value-of select="substring-before($str, $sep)"/></li>

            <xsl:call-template name="splitter">

                <xsl:with-param name="str" select="substring-after($str, $sep)"/>

                <xsl:with-param name="sep" select="$sep"/>

            </xsl:call-template>

        </xsl:when>

        <xsl:otherwise>

            <li><xsl:value-of select="$str"/></li>

        </xsl:otherwise>

    </xsl:choose>

    

</xsl:template></xsl:stylesheet>

of course, it is a lot easier if you could use XSLT2
<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

    version="2.0">

    <xsl:variable name="keyword">keyword1;keyword2;keyword3</xsl:variable>

    <xsl:template match="/">

        <ul>

            <xsl:for-each select="tokenize($keyword, ';')">

                <li><xsl:value-of select="."/></li>

            </xsl:for-each>

        </ul>

    </xsl:template>

</xsl:stylesheet>

Note that I pasted the string in a variable, ofcourse you can call the tokenize() or the named template directly on the attribute

Thanks, but I am not exactly understanding.  I tried your code in mine and it has a problem putting an xsl:template inside another template.  Also, what did you say about tokenize?  Sorry, I am really having trouble with this.

how could I do it with
<xsl:value-of select="@Keyword"/>
<xsl:template name="dvt_1.rowview">

<tr>

<td>			

<table border="1" cellspacing="0" width="100%">

<tr>

<td>

Title: <xsl:value-of select="@Title"/><br />

Description: <xsl:value-of select="@KpiDescription"/><br />

Keyword: <xsl:value-of select="@Keyword"/><br />



<xsl:variable name="keyword">keyword1;keyword2;keyword3</xsl:variable>

<xsl:template match="/">

<ul>

<xsl:for-each select="tokenize($keyword, ';')">

<li><xsl:value-of select="."/></li>

</xsl:for-each>

</ul>

</xsl:template>

mmh, am I wrong in assuming you are a real beginner?

templates can not be nested
you should put them next to each-other

This sounds like sharepoint, is it?
So you are bound to XSLT1, you cannot use tokenize() then

Here is how you should organize the templates
    <xsl:template name="dvt_1.rowview">

        <tr>

            <td>			

                <table border="1" cellspacing="0" width="100%">

                    <tr>

                        <td>

                            Title: <xsl:value-of select="@Title"/><br />

                            Description: <xsl:value-of select="@KpiDescription"/><br />

                            Keyword: <br />

                            <ul>

                                <xsl:call-template name="splitter">

                                    <xsl:with-param name="str" select="@Keyword"/>

                                    <xsl:with-param name="sep" select="';'"/>

                                </xsl:call-template>

                            </ul>

                        </td>

                    </tr>

                </table>

            </td>

        </tr>

    </xsl:template>

    

    <xsl:template name="splitter">

        <xsl:param name="str"/>

        <xsl:param name="sep"/>

        <xsl:choose>

            <xsl:when test="contains($str, $sep)">

                <li><xsl:value-of select="substring-before($str, $sep)"/></li>

                <xsl:call-template name="splitter">

                    <xsl:with-param name="str" select="substring-after($str, $sep)"/>

                    <xsl:with-param name="sep" select="$sep"/>

                </xsl:call-template>

            </xsl:when>

            <xsl:otherwise>

                <li><xsl:value-of select="$str"/></li>

            </xsl:otherwise>

        </xsl:choose>

    </xsl:template>

Yes SharePoint, YES to beginner (at least with xslt).  I would much rather do this via code instead of xslt.  Thanks, I will try this.

oh, you could do this with javascript inside your XSLT since you are using the microsoft XSLT processor,
but that would be even more tricky
