    <p>The problem is that the context changes in your <code>analyze-string</code> element. Maybe the following solution will help you.</p> <p>For an XML file like that : </p> <pre><code>&lt;a&gt; &lt;Format&gt; &lt;TagNr&gt;92&lt;/TagNr&gt; &lt;Option&gt;A&lt;/Option&gt; &lt;Format&gt;//[N]15d&lt;/Format&gt; &lt;/Format&gt; &lt;Format&gt; &lt;TagNr&gt;92&lt;/TagNr&gt; &lt;Option&gt;B&lt;/Option&gt; &lt;Format&gt;//3!a/3!a/15d&lt;/Format&gt; &lt;/Format&gt; &lt;Tag&gt; &lt;TagNr&gt;92&lt;/TagNr&gt; &lt;Options&gt;AB&lt;/Options&gt; &lt;/Tag&gt; &lt;/a&gt; </code></pre> <p>Consider the following XSLT :</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:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="2.0"&gt; &lt;xsl:output indent="yes"/&gt; &lt;xsl:key name="xx" match="//Format/Format" use="concat(../TagNr, ../Option)"/&gt; &lt;xsl:template match="/"&gt; &lt;result&gt; &lt;xsl:apply-templates select="//Tag"/&gt; &lt;/result&gt; &lt;/xsl:template&gt; &lt;xsl:template match="Tag"&gt; &lt;xsl:call-template name="createOPT"&gt; &lt;xsl:with-param name="str" as="xs:string" select="Options"/&gt; &lt;/xsl:call-template&gt; &lt;/xsl:template&gt; &lt;xsl:template name="createOPT"&gt; &lt;xsl:param name="str"/&gt; &lt;xsl:if test="string-length($str) &gt; 0"&gt; &lt;xsl:variable name="firstChar" select="substring($str,1,1)"/&gt; &lt;xsl:variable name="TNO" select="concat(TagNr,$firstChar)"/&gt; &lt;opt&gt; &lt;tag&gt;&lt;xsl:value-of select="$TNO"/&gt;&lt;/tag&gt; &lt;fmt&gt;&lt;xsl:value-of select="key('xx', $TNO)"/&gt;&lt;/fmt&gt; &lt;/opt&gt; &lt;xsl:call-template name="createOPT"&gt; &lt;xsl:with-param name="str" select="substring($str,2)"/&gt; &lt;/xsl:call-template&gt; &lt;/xsl:if&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p>The result is : </p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;result&gt; &lt;opt&gt; &lt;tag&gt;92A&lt;/tag&gt; &lt;fmt&gt;//[N]15d&lt;/fmt&gt; &lt;/opt&gt; &lt;opt&gt; &lt;tag&gt;92B&lt;/tag&gt; &lt;fmt&gt;//3!a/3!a/15d&lt;/fmt&gt; &lt;/opt&gt; &lt;/result&gt; </code></pre>

    1. COThanks - this definitely gets me going again! And also supplies me with a means of substringing char by char which I originally wished to do. One question though: context is lost but why? And why is there no more elegant solution as mentioned in another thread on this site: define variable to regain context?

    2. COYou can also work with a variable to regain context. Maybe it's more elegant. My humble personal view is that `analyze-string` is a bit akward to use and maintain, I prefer to avoid it when it's possible.

    3. COThe context is not lost, however inside the analyze-string it is not a node but rather an atomic item, namely the (sub)string that is currently being processed.

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).
