    <p>I am trying to set a variable in XSLT 1.0 as follows </p> <pre><code> &lt;xsl:variable name="by" select="Contributors/Contributor[Role='ReMixer']/Name | Attribution" /&gt; </code></pre> <p>The Idea is that if the Remixer Role does not exsit then the variable will take on the value of Attribution, however when testing it always takes on the value Attribution regardless.</p> <p>any ideas why this happens and a solution?</p> <p>update 1</p> <p>This is currently what i've got working</p> <pre><code>&lt;xsl:variable name="Remixer" select="Contributors/Contributor[Role='ReMixer']/Name" /&gt; &lt;xsl:variable name="by"&gt; &lt;xsl:choose&gt; &lt;xsl:when test="$Remixer = ''"&gt; &lt;xsl:value-of select="Attribution"/&gt; &lt;/xsl:when&gt; &lt;xsl:otherwise&gt; &lt;xsl:value-of select="$Remixer"/&gt; &lt;/xsl:otherwise&gt; &lt;/xsl:choose&gt; &lt;/xsl:variable&gt; </code></pre> <p>Would there be a shorter way of acheving the same results?</p> <p>below is a copy of the xml doccument</p> <pre><code>&lt;track&gt; &lt;attribution&gt;Various Artists&lt;/attribution&gt; &lt;contributors&gt; &lt;contributor primary="true"&gt; &lt;role&gt;Recording Artist&lt;/role&gt; &lt;name country="" birth-deathyear="" part3="Cosmic Gate" part2="" part1=""&gt;Cosmic Gate&lt;/name&gt; &lt;/contributor&gt; &lt;contributor primary="true"&gt; &lt;role&gt;ReMixer&lt;/role&gt; &lt;name country="" birth-deathyear="" part3="Gary Gee" part2="" part1=""&gt;Gary Gee&lt;/name&gt; &lt;/contributor&gt; &lt;/contributors&gt; &lt;/track&gt; </code></pre> <p>Thanks</p> <p>Sam</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
