Looping and page selection in XSLT problem

Hi All,

I have the following XSLT code:

<?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 match="/">

<xsl:for-each select="$currentPage/ancestor-or-self::* [name()='Event' and umbraco.library:DateGreaterThanOrEqualToday(./eventDate)]">
<div class="event_1_main">
  <div class="event_img"><img src="/images/event_img_2.jpg" alt="" /></div>
    <div class="event_right_part">
       <h2 class="event_title"><xsl:value-of select="current()/@nodeName"/></h2>
        <div class="event_text">
        <strong><xsl:value-of select="current()/eventDate"/></strong><br />
          <xsl:value-of select="current()/eventDescription"/>
        </div>
      <div class="viewmore_btn"><a href="{umbraco.library:NiceUrl(current()/@id)}">VIEW MORE</a></div>
    </div>
</div>
</xsl:for-each>

</xsl:template>

</xsl:stylesheet>

and it displays nothing on my page. What is the correct way to select child elements of the current page by type?

I will also need to perform a similar selection in another piece of code, so how does one select elements from under a specific node?

Hi Geoff,

Try this slight refactoring for a simple way to illustrate this:

<xsl:template match="/">

    <xsl:apply-templates select="$currentPage/ancestor-or-self::Event[umbraco.library:DateGreaterThanOrEqualToday(eventDate)]" />

</xsl:template>

<!-- Template for an Event node -->
<xsl:template match="Event">
    <div class="event_1_main">
        <div class="event_img">
            <img src="/images/event_img_2.jpg" alt="" />
        </div>
            <div class="event_right_part">
                <h2 class="event_title">
                    <xsl:value-of select="@nodeName"/>
                </h2>
                <div class="event_text">
                    <strong>
                        <xsl:value-of select="eventDate"/>
                    </strong>
                    <br />
                    <xsl:value-of select="eventDescription"/>
                </div>
            <div class="viewmore_btn">
                <a href="{umbraco.library:NiceUrl(@id)}">VIEW MORE</a>
            </div>
        </div>
    </div>
</xsl:template>

Note that once you're inside a template (or a for-each for that matter) you can just refer to child elements without any prefix (current() or ./ etc.) at all.

Alright, thanks for your help.

I'm having trouble getting an image to display in this loop.
```
<img src="{umbraco.library:GetMedia(current()/eventImage, true())}" alt="" />
```
Gives me "/media/15926/banner.jpg67326887970jpg" - "67326887970jpg" should not be there. What am I doing wrong?

Thanks.

Hi Geoff,

Seems like you are picking the image from the media secion. You could try this chaging this
```
<imgsrc="{umbraco.library:GetMedia(current()/eventImage, true())}"alt=""/>
```
to
```
<img src="{umbraco.library:GetMedia(eventImage, 'true')/umbracoFile}" alt=""/>
```
