    <p>I am attempting to perform some text canonicalization to replace some contractions. Here is some example input:</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;transcript&gt; &lt;p id="p1"&gt; &lt;s id="s1"&gt;&lt;w&gt;Here&lt;/w&gt;&lt;w&gt;'s&lt;/w&gt; &lt;w&gt;an&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;, &lt;w&gt;let&lt;/w&gt;&lt;w&gt;'s&lt;/w&gt; &lt;w&gt;consider&lt;/w&gt; &lt;w&gt;it&lt;/w&gt;&lt;/s&gt; &lt;s id="s2"&gt;&lt;w&gt;Here&lt;/w&gt; &lt;w&gt;'s&lt;/w&gt; &lt;w&gt;an&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;, &lt;w&gt;let&lt;/w&gt;&lt;w&gt;'s&lt;/w&gt; &lt;w&gt;consider&lt;/w&gt; &lt;w&gt;it&lt;/w&gt;&lt;/s&gt; &lt;s id="s3"&gt;&lt;foo&gt;&lt;w&gt;Here&lt;/w&gt;&lt;/foo&gt;&lt;bar&gt;&lt;w&gt;'s&lt;/w&gt;&lt;/bar&gt; &lt;w&gt;an&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;, &lt;foo&gt;&lt;w&gt;let&lt;/w&gt;&lt;/foo&gt;&lt;w&gt;'s&lt;/w&gt; &lt;w&gt;consider&lt;/w&gt; &lt;w&gt;it&lt;/w&gt;&lt;/s&gt; &lt;s id="s4"&gt;&lt;w&gt;Here&lt;/w&gt;&lt;bar&gt;&lt;baz&gt;&lt;w&gt;'s&lt;/w&gt;&lt;/baz&gt;&lt;/bar&gt; &lt;w&gt;an&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;, &lt;baz&gt;&lt;bar&gt;&lt;w&gt;let&lt;/w&gt;&lt;/bar&gt;&lt;w&gt;'s&lt;/w&gt;&lt;/baz&gt; &lt;w&gt;consider&lt;/w&gt; &lt;w&gt;it&lt;/w&gt;&lt;/s&gt; &lt;s id="s5"&gt;&lt;w&gt;Look&lt;/w&gt; &lt;w&gt;here&lt;/w&gt;&lt;/s&gt; &lt;s id="s6"&gt;&lt;w&gt;'s&lt;/w&gt; &lt;w&gt;another&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;&lt;/s&gt; &lt;/p&gt; &lt;/transcript&gt; </code></pre> <p>In this example, I want to replace "here's" with "hers is" and "let's" with "let us". Thus, my desired output is,</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;transcript&gt; &lt;p id="p1"&gt; &lt;s id="s1"&gt;&lt;w&gt;Here&lt;/w&gt; &lt;w&gt;is&lt;/w&gt; &lt;w&gt;an&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;, &lt;w&gt;let&lt;/w&gt; &lt;w&gt;us&lt;/w&gt; &lt;w&gt;consider&lt;/w&gt; &lt;w&gt;it&lt;/w&gt;&lt;/s&gt; &lt;s id="s2"&gt;&lt;w&gt;Here&lt;/w&gt; &lt;w&gt;is&lt;/w&gt; &lt;w&gt;an&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;, &lt;w&gt;let&lt;/w&gt; &lt;w&gt;us&lt;/w&gt; &lt;w&gt;consider&lt;/w&gt; &lt;w&gt;it&lt;/w&gt;&lt;/s&gt; &lt;s id="s3"&gt;&lt;foo&gt;&lt;w&gt;Here&lt;/w&gt;&lt;/foo&gt; &lt;bar&gt;&lt;w&gt;is&lt;/w&gt;&lt;/bar&gt; &lt;w&gt;an&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;, &lt;foo&gt;&lt;w&gt;let&lt;/w&gt;&lt;/foo&gt; &lt;w&gt;us&lt;/w&gt; &lt;w&gt;consider&lt;/w&gt; &lt;w&gt;it&lt;/w&gt;&lt;/s&gt; &lt;s id="s4"&gt;&lt;w&gt;Here&lt;/w&gt; &lt;bar&gt;&lt;baz&gt;&lt;w&gt;is&lt;/w&gt;&lt;/baz&gt;&lt;/bar&gt; &lt;w&gt;an&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;, &lt;baz&gt;&lt;bar&gt;&lt;w&gt;let&lt;/w&gt;&lt;/bar&gt; &lt;w&gt;us&lt;/w&gt;&lt;/baz&gt; &lt;w&gt;consider&lt;/w&gt; &lt;w&gt;it&lt;/w&gt;&lt;/s&gt; &lt;s id="s5"&gt;&lt;w&gt;Look&lt;/w&gt; &lt;w&gt;here&lt;/w&gt;&lt;/s&gt; &lt;s id="s6"&gt;&lt;w&gt;'s&lt;/w&gt; &lt;w&gt;another&lt;/w&gt; &lt;w&gt;example&lt;/w&gt;&lt;/s&gt; &lt;/p&gt; &lt;/transcript&gt; </code></pre> <p>I was able to put together some (probably nothing near elegant or optimal) code that can handle <code>s1</code> and <code>s2</code>, but I do not see that I can generalize it to something useful.</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"&gt; &lt;xsl:output method="xml"/&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;xsl:template match="w[translate(text(),'S','s')=&amp;quot;'s&amp;quot;][preceding-sibling::*[1]/self::w[translate(text(),'HERE','here')='here']]"&gt; &lt;xsl:text&gt; &lt;/xsl:text&gt; &lt;xsl:copy&gt;&lt;xsl:copy-of select="@*"/&gt;is&lt;/xsl:copy&gt; &lt;/xsl:template&gt; &lt;xsl:template match="w[translate(text(),'S','s')=&amp;quot;'s&amp;quot;][preceding-sibling::*[1]/self::w[translate(text(),'LET','let')='let']]"&gt; &lt;xsl:text&gt; &lt;/xsl:text&gt; &lt;xsl:copy&gt;&lt;xsl:copy-of select="@*"/&gt;us&lt;/xsl:copy&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p>Some details:</p> <ul> <li><p>Assume words are all wrapped in <code>&lt;w&gt;</code> tags and that the "words" of interest are consecutive (though not necessarily siblings)</p></li> <li><p>Arbitrary tags may wrap one or the other or both of the word and the 's.</p></li> <li><p>The substitution should not cross sentence <code>&lt;s&gt;</code> boundaries (as shown in s5 and s6) - though if this is impossible, I will not cry.</p></li> <li><p>If a space already exists between word and 's, I still want to replace the 's.

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).
