    <p>I have the following XML.</p> <pre><code> &lt;body&gt; &lt;p type="Heading 1"&gt;My Heading&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text... &lt;p type="Key Words"&gt;This is a keyword A&lt;/p&gt;&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text... &lt;p type="Key Words"&gt;This is a keyword B&lt;/p&gt;&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p type="Heading 1"&gt;My Next Heading&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... &lt;p type="Key Words"&gt;This is a keyword C&lt;/p&gt;This is paragraph text...&lt;/p&gt; &lt;p type="Heading 2"&gt;My Next Heading&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... &lt;p type="Key Words"&gt;This is a keyword D&lt;/p&gt; This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;/body&gt; </code></pre> <p>I would like to move all of the "Key Words" to just before the next heading as shown below:</p> <pre><code>&lt;body&gt; &lt;p type="Heading 1"&gt;My Heading&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p type="Key Words"&gt;This is a keyword A&lt;/p&gt; &lt;p type="Key Words"&gt;This is a keyword B&lt;/p&gt; &lt;p type="Heading 1"&gt;My Next Heading&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p type="Key Words"&gt;This is a keyword C&lt;/p&gt; &lt;p type="Heading 2"&gt;My Next Heading&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p&gt;This is paragraph Text... This is paragraph text...&lt;/p&gt; &lt;p type="Key Words"&gt;This is a keyword D&lt;/p&gt; &lt;/body&gt; </code></pre> <p>I have code that works, but it has serious performance problems because I am running this transform on documents that have 10's of thousands of words. Below is my current code.</p> <pre><code>&lt;!-- Place all keywords in section right before the next heading title. --&gt; &lt;xsl:template match="p[contains(@type,'Heading')]"&gt; &lt;xsl:variable name="headingCount" &gt; &lt;xsl:value-of select="count(preceding::p[contains(@type,'Heading')])"/&gt; &lt;/xsl:variable&gt; &lt;xsl:variable name="precedingKeyWordCount"&gt; &lt;xsl:value-of select="count(preceding::p[contains(@type,'Key Words') and count(preceding::p[contains(@type,'Heading')]) = $headingCount])"/&gt; &lt;/xsl:variable&gt; &lt;xsl:if test="$precedingKeyWordCount &gt; 0" &gt; &lt;p type="Key Words"&gt; &lt;xsl:apply-templates select="preceding::p[contains(@type,'Key Words') and count(preceding::p[contains(@type,'Heading')]) = $headingCount]" /&gt; &lt;/p&gt; &lt;/xsl:if&gt; &lt;!-- place original heading --&gt; &lt;xsl:copy&gt; &lt;xsl:apply-templates select="@*|node()"/&gt; &lt;/xsl:copy&gt; &lt;/xsl:template&gt; </code></pre> <p>Does anyone know a more efficient way to accomplish this?</p> <p>Thank you.</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
