    <p>I'm trying to transform old XML files into a new and improved structure. Part of this needs me to wrap some loose elements into a parent container, as well as modify their children</p> <p><strong>Old structure</strong></p> <pre><code>&lt;monograph&gt; &lt;title&gt;asdf&lt;/title&gt; &lt;dosage.sec id="dosage.sec.1"&gt; &lt;dosage.sec&gt;asgfd&lt;/dosage.sec&gt; &lt;dosage.sec&gt;asgfd&lt;/dosage.sec&gt; &lt;/dosage.sec&gt; &lt;dosage.sec id="dosage.sec.2"&gt; &lt;dosage.sec&gt;asgfd&lt;/dosage.sec&gt; &lt;dosage.sec&gt;asgfd&lt;/dosage.sec&gt; &lt;/dosage.sec&gt; &lt;dosage.sec id="dosage.sec.3"&gt; &lt;dosage.sec&gt;asgfd&lt;/dosage.sec&gt; &lt;dosage.sec&gt;asgfd&lt;/dosage.sec&gt; &lt;/dosage.sec&gt; &lt;products&gt; &lt;prod&gt;sadf&lt;/prod&gt; &lt;prod&gt;sadf&lt;/prod&gt; &lt;/products&gt; &lt;/monograph&gt; </code></pre> <p><strong>New structure</strong></p> <pre><code>&lt;monograph&gt; &lt;title&gt;asdf&lt;/title&gt; &lt;dosage&gt; &lt;dosage.sec id="dosage.sec.1"&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;/dosage.sec&gt; &lt;dosage.sec id="dosage.sec.2"&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;/dosage.sec&gt; &lt;dosage.sec id="dosage.sec.3"&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;/dosage.sec&gt; &lt;/dosage&gt; &lt;products&gt; &lt;prod&gt;sadf&lt;/prod&gt; &lt;prod&gt;sadf&lt;/prod&gt; &lt;/products&gt; &lt;/monograph&gt; </code></pre> <p>I found this <a href="https://stackoverflow.com/questions/3962161/how-can-i-wrap-a-group-of-adjacent-elements-using-xslt">answer</a> and modified it a bit to suit my needs:</p> <pre><code>&lt;!-- wrap dosage.sec elements in a dosage container --&gt; &lt;xsl:template match="node()|@*" name="dosage.sec"&gt; &lt;xsl:copy&gt; &lt;xsl:apply-templates select="node()|@*" /&gt; &lt;/xsl:copy&gt; &lt;/xsl:template&gt; &lt;xsl:template match="monograph/dosage.sec[not(preceding-sibling::*[1][self::dosage.sec])]"&gt; &lt;dosage&gt; &lt;xsl:call-template name="dosage.sec" /&gt; &lt;xsl:apply-templates mode="copy" select="following-sibling::*[1][self::dosage.sec]" /&gt; &lt;/dosage&gt; &lt;/xsl:template&gt; &lt;xsl:template match="monograph/dosage.sec" mode="copy"&gt; &lt;xsl:call-template name="dosage.sec"/&gt; &lt;/xsl:template&gt; &lt;!-- rename children dosage.sec --&gt; &lt;xsl:template match="dosage.sec/dosage.sec"&gt; &lt;dosage.qual&gt; &lt;xsl:apply-templates /&gt; &lt;/dosage.qual&gt; &lt;/xsl:template&gt; </code></pre> <p>But my output is:</p> <pre><code>&lt;monograph&gt; &lt;title&gt;asdf&lt;/title&gt; &lt;dosage&gt; &lt;dosage.sec id="dosage.sec.1"&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;/dosage.sec&gt; &lt;dosage.sec id="dosage.sec.2"&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;/dosage.sec&gt; &lt;dosage.sec id="dosage.sec.3"&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;/dosage.sec&gt; &lt;/dosage&gt; &lt;dosage.sec id="dosage.sec.3"&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;dosage.qual&gt;asgfd&lt;/dosage.qual&gt; &lt;/dosage.sec&gt; &lt;products&gt; &lt;prod&gt;sadf&lt;/prod&gt; &lt;prod&gt;sadf&lt;/prod&gt; &lt;/products&gt; &lt;/monograph&gt; </code></pre> <p>I'm using PHP5's built-in XSLTProcessor object - all XML and XSL are version 1.0</p>

    1. COYour XSLT would probably work if you removed the `[1]` from this line: `<xsl:apply-templates mode="copy" select="following-sibling::*[1][self::dosage.sec]" />` but the way you're going about it may not be the best approach.

    2. COThe answer you referred to was addressing a particular scenario where they needed to wrap items that had different items before and after them. Do you have a requirement like that, or is it as straightforward as your example?

    3. COAll of the dosage.sec elements should be contiguous within the source document (no other elements in between), so it is simpler. I've modified my example, as I realised that I didn't accurately depict that I have other elements in the monograph before and after the block of dosage.sec

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.
