    String to List

    Guys,

    I have a macro called 'TextToList' which has a parameter 'Text'.
    The parameter is filled with the contents of a Multiline Textbox.

    In the macro/xsl i want to split the Text on 'new-lines' ('\n' of '\r' ???)
    Then in a loop i want to create a html list (<ul><li>foo</li><li>bar</li></ul>) with the individual lines.

    I found already something like this:

     <xsl:variable name="newlist" select="concat(normalize-space($textToList), '\r')" />
     <xsl:variable name="first" select="substring-before($newlist, '\r')" />
     <xsl:variable name="remaining" select="substring-after($newlist, '\r')" />
     <id>
      <li><xsl:value-of select="$first" /></li>
     </id>
     <xsl:if test="$remaining">        
      <xsl:call-template name="default">
       <xsl:with-param name="list" select="$remaining" />
      </xsl:call-template>
     </xsl:if>

    But i can't make it work.

    Can someone help me with this?

    Hi,

    The best method to use is probably umbraco.library:Split

    Something like:

    <xsl:variable name="newlist" select="concat(normalize-space($textToList), '\r')" />  <!-- assuming $textToList already contains the macro parameter? -->
    <xsl:variable name="listSplit" select="umbraco.library:Split($newlist, '\n')" />
    <ul>
    <xsl:for-each select="$listSplit/value">
     <li><xsl:value-of select="." /></li>
    <xsl:for-each>
    </ul>

    Probably best done with templates but this is just a quick/dirty example :)

    Also, if you find \n doesn't work, I've personally had better luck with '&#xa;', guess it depends on other factors though.

    -Tom

    Tom,

    thanks for your reply. It didn't work with '\r', '\n', and &#xa; and &#xd;

    but i solved the problem: Instead of a textarea i used the tags type and a little XSLT.

    <xsl:variable name="newlist" select="normalize-space($textToList)" />   <!-- assuming $textToList already contains the macro parameter?, and that assumption is right! ;-) -->
     <xsl:variable name="listSplit" select="umbraco.library:Split($newlist, ',') " />
     <ul>
      <xsl:for-each select="$listSplit/value">
       <li><xsl:value-of select="." /></li>
      </xsl:for-each>
     </ul>
