    Splitting a Number

    Hi guys,

    Was wondering if anybody could help me with this, its a bit of an odd one!

    I want to split a value, in to its separate elements. So 123, would become 123. 

    Somethings like...

    <xsl:variable name="value" select="123">

<xsl:variable name="valueTransform" select="magic-transform($123)" />

which would give an output like

<number>
    <node>1</node>
    <node>2</node>
    <node>3</node>
</number>

    The rational behind this, is splitting numbers so they can each be assigned a css-class ready for image replacement.

    So the number becomes a pretty image, but its still accessible!

    Any pointers much appreciated! Laurie

    Hi Laurence,

    Do you have control over the value "123"? Could you comma-separate them? "1,2,3"?

    If so, then you could use umbraco.library:Split() to do what you need.

    Cheers, Lee.

    No, sadly not its a two digit week number. /L (so ranges from 0 - 52)

    Hi Laurence, I'm not completely sure know what your input is - a 2-digit week number you want to split into 2 separate digits, or a string of 2-digit  weeknumbers you want to split into separate weeknumbers, or ...

    Anyway, you could consider using the xslt substring function (http://msdn.microsoft.com/en-us/library/ms256054.aspx)

    Laurence...

    can you use to grab specific indexes of the string?

    <xsl:value-of select="substring(.,1,1)"/>

    Hi Laurence,

    If you're in a position to use an XSLT extension, try this:

    public static XPathNodeIterator StringToCharArray(string StringToSplit)
{
    char[] values = StringToSplit.ToCharArray();
    XmlDocument xd = new XmlDocument();
    xd.LoadXml("<chars/>");
    foreach (char value in values)
    {
        XmlNode node = xmlHelper.addTextNode(xd, "char", value.ToString());
        xd.DocumentElement.AppendChild(node);
    }
    return xd.CreateNavigator().Select("/chars");
}

    Works the same say as umbraco.library.Split(), but turns the string into a Char array.

    Cheers, Lee.

    To confirm, this is an example...

    INPUT = 42

    I want to split this into 4 and 2.

    So I can output

    <span class="digit4">4</span>
    <span class="digit2">2</span>

    Thanks for the responses so far! I will look into this more, but its Friday I'm off out for drinks and good times! :) Hope you are too :)

    Have a lovely weekend, will try some of the above tomorrow :) Laurie

    Hi Laurence,

    This recursive template will do the trick:

       <xsl:template name="split">
        <xsl:param name="number" />
        <xsl:param name="index" select="1" />
        <xsl:variable name="digit" select="substring($number, 1, 1)" />
        <span class="digit{$digit}">
            <xsl:value-of select="$digit" />
        </span>
        <xsl:if test="$index &lt; string-length($number)">
            <xsl:call-template name="split">
                <xsl:with-param name="number" select="substring($number, 2)" />
            </xsl:call-template>
        </xsl:if>
    </xsl:template>

    <!-- Sample call from somewhere else: -->
    <xsl:call-template name="split">
        <xsl:with-param name="number" select="42" />
    </xsl:call-template>

    - and a god weekend to you too :-)

    Hi Laurence, you can use the EXSLT string function split (or tokenize) with an empty string, which will separate the string into each character see here: http://www.exslt.org/str/functions/split/str.split.html

    In use it would be:

    <xsl:variable name="value" select="123">
    <xsl:variable name="valueTransform" select="Exslt.ExsltStrings:split($value,'')" />

    which would give the following node set in the $valueTransform variable:

    <token>1</token>
    <token>2</token>
    <token>3</token>

    Not sure if the umbraco.library:Split function works in the same way, but the EXSLT one certainly claims to.

    I do have to say that Chriztian's solution will do exactly what you are asking for,

    Really like the solutions suggested with particular note too Chriztian's and Josh's.

    Many thanks! Laurie
