Creating some kind of "for-loop"

Hello guys,

I'm still learning my way through Umbraco/XSLT.
I created a xslt macro, for a form, which has some kind of date pickers made with select tags from HTML.
Now I want to create some kind of loop that checks all the (option) from my select, and if the (option) matches the current month, that (option) is the "selected" one.

So, what I am aiming for here is:

- get the current month (Already achieved this );
- loop through all the 12 month (option);
- If (option value="currentMonth"), then selected="selected"

Thank you in advance!

Hi Gonçalo,

Here's how I'd probably start:

<!-- Construct a "months" XML variable that we can use XPath on -->
<xsl:variable name="monthsProxy">
    <month id="01">January</month>
    <month id="02">February</month>
    <month id="03">March</month>
    <month id="04">April</month>
    <month id="05">May</month>
    <month id="06">June</month>
    <month id="07">July</month>
    <month id="08">August</month>
    <month id="09">September</month>
    <month id="10">October</month>
    <month id="11">November</month>
    <month id="12">December</month>
</xsl:variable>
<xsl:variable name="months" select="msxml:node-set($monthsProxy)" />

<!-- Get "today" as an XMLDate (e.g.: 2014-12-16T20:20:00) -->
<xsl:variable name="today" select="umbraco.library:CurrentDate()" />
<!-- Extract the month  -->
<xsl:variable name="currentMonth" select="substring($today, 6, 2)" />

<xsl:template match="/">
    <select name="month">
        <!-- Create an `<option>` tag for every month... -->
        <xsl:for-each select="$months/month">
            <option value="{@id}">
                <!-- Add the selected attribute if this is the current month -->
                <xsl:if test="@id = $currentMonth"><xsl:attribute name="selected">selected</xsl:attribute></xsl:if>
                <xsl:value-of select="." />
            </option>
        </xsl:for-each>
    </select>
</xsl:template>

Hope that gets you started too,

/Chriztian
