    <p>I'm trying to use parentheses to override default operator precedence in an xpath expression within an xslt with no luck. For example:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" ?&gt; &lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:exsl="http://exslt.org/common" extension-element-prefixes="exsl" version="1.0"&gt; &lt;xsl:output encoding="utf-8" standalone="yes"/&gt; &lt;xsl:template match="/"&gt; &lt;xsl:apply-templates select="*"/&gt; &lt;/xsl:template&gt; &lt;xsl:template match="@* | node()"&gt; &lt;xsl:copy&gt; &lt;xsl:apply-templates select="@* | node()"/&gt; &lt;/xsl:copy&gt; &lt;/xsl:template&gt; &lt;!--these should work but don't--&gt; &lt;xsl:template match="//(X|Y|Z)/AABBCC"/&gt; &lt;xsl:template match="(book/author)[last()]"/&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p>Visual Studio 2010 won't compile this returning:</p> <p>Unexpected token '(' in the expression. // -->(&lt;-- X|Y|Z)/AABBCC</p> <p>Unexpected token '(' in the expression. -->(&lt;-- book/author)[last()]</p> <p>Yet the second example is from MSDN:</p> <p><a href="http://msdn.microsoft.com/en-us/library/ms256086.aspx">http://msdn.microsoft.com/en-us/library/ms256086.aspx</a></p> <p>and numerous references say you can use parentheses in this way:</p> <p><a href="http://saxon.sourceforge.net/saxon6.5.3/expressions.html">http://saxon.sourceforge.net/saxon6.5.3/expressions.html</a></p> <p><a href="http://www.stylusstudio.com/xsllist/200207/post90450.html">http://www.stylusstudio.com/xsllist/200207/post90450.html</a></p> <p><a href="http://www.mulberrytech.com/quickref/XSLT_1quickref-v2.pdf">http://www.mulberrytech.com/quickref/XSLT_1quickref-v2.pdf</a></p> <p>Is this an xpath 1.0 vs 2.0 thing...or is there something else i'm missing? If it's an xpath 2.0 thing, is there a nice xpath 1.0 way to do the same thing?</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.
