Convert multiple lines to unordered list

Is it possible, with XSLT, to take a number of lines in a multi-line text (Textbox Multiple) and convert each line into a <li> item?

Rumors on the web say, it is possible, but example didn't work for me, so i switched to a .net control.

Hi Gordon,

Try this XSLT:
```
<xsl:variable name="lines" select="umbraco.library:Split(data[@alias='bodyText'], '&#xD;')" />
<xsl:if test="count($lines/value) &gt; 0">
    <ul>
        <xsl:for-each select="$lines/value">
            <li>
                <xsl:value-of select="." />
            </li>
        </xsl:for-each>
    </ul>
</xsl:if>
```
The "" entity is for new-lines... but as far as I'm aware it is only for /r (not /r/n - as in Windows), although this should give you the desired result!

Remember to change the "data[@alias='bodytext']" with whatever is containing your multi-line content.

Cheers,

- Lee

A recursive template should do the trick (modify the param statement to select the property holding your multiline textbox):

<!-- Recursive template to write statements from a textarea property (e.g., newline-separated values) to successive <li> elements -->
<xsl:template name="output-statements">
    <xsl:param name="statements" select="data[@alias = 'statements']" />
    <xsl:if test="contains($statements, '&#x0A;')">
        <li>
            <xsl:value-of select="substring-before($statements, '&#x0A;')" />
        </li>
        <xsl:call-template name="output-statements">
            <xsl:with-param name="statements" select="substring-after($statements, '&#x0A;')" />
        </xsl:call-template>
    </xsl:if>
    <xsl:if test="normalize-space($statements)">
        <li>
            <xsl:value-of select="$statements" />
        </li>
    </xsl:if>
</xsl:template>

You execute it with the call-template instruction from:

<xsl:call-template name="output-statements" />

Yep, this is possible - but very flakey. The two examples above should work for most situations, but I've seen linebreaks use "" and "
" both separately and together in the same line.

It's important to remember that the chars for linebreaks will differ between OS' -> http://www.osix.net/modules/article/?id=93

Here's another (!) alternative solution, for text entered on a windows machine

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
   version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
 xmlns:msxml="urn:schemas-microsoft-com:xslt"
  xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" 
  exclude-result-prefixes="msxml umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">


<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:template name="newLineToLi">
 <xsl:param name="contentToChange" />
    <li><xsl:value-of select='umbraco.library:Replace($contentToChange, "&#xa;", "&lt;/li&gt;&lt;li&gt;")' disable-output-escaping="yes" /></li>
</xsl:template>

<xsl:template match="/">
<xsl:call-template name="newLineToLi">
 <xsl:with-param name="contentToChange" select="$currentPage/data [@alias='metaDescription']" />
</xsl:call-template>
</xsl:template>

</xsl:stylesheet>

- just a quick note on linefeeds in XML: An XML parser is required to normalize linefeed/carriage-return sequences to a single linefeed character (
), before handing the document over to the receiver. So whether we're on Windows, Linux or Mac OS we should actually be able to easily recognize any newline character in content.

Another alternative, not sure on relative speeds... this one using regexp...

<xsl:template match="/">
  <ul>
   <li>
  <xsl:value-of disable-output-escaping="yes" select="Exslt.ExsltRegularExpressions:replace($currentPage/*[name() = $property], '(
)+', 'Gi', '</li><li>')"/>
  </li>
  </ul>
</xsl:template>
