    <p>I am using xslt 2.0, I have following sample xml, I want to get all "header-lightgray" nodes between the two "header-gray" nodes, the problem here is: I don't know how many "header-lightgray" there. so I can not use position() function. and xsl for each don't support break.</p> <pre><code>&lt;t&gt; &lt;parent class="header-gray"&gt;&lt;/parent&gt; &lt;parent class="header-lightgray"&gt;&lt;/parent&gt; &lt;parent class="header-lightgray"&gt;&lt;/parent&gt; &lt;parent class="header-lightgray"&gt;&lt;/parent&gt; ... &lt;parent class="header-gray"&gt;&lt;/parent&gt; &lt;parent class="header-lightgray"&gt;&lt;/parent&gt; &lt;parent class="header-lightgray"&gt;&lt;/parent&gt; &lt;parent class="header-lightgray"&gt;&lt;/parent&gt; &lt;parent class="header-gray"&gt;&lt;/parent&gt; &lt;/t&gt; </code></pre> <p>I want go through them and replace all nodes, header-gray with div and header-lightgray with span. the output expected is:</p> <pre><code>&lt;div class="header-gray"&gt; &lt;span class="header-lightgray"/&gt; &lt;span class="header-lightgray"/&gt; &lt;span class="header-lightgray"/&gt; ... &lt;/div&gt; &lt;div class="header-gray"&gt; &lt;span class="header-lightgray"/&gt; &lt;span class="header-lightgray"/&gt; &lt;span class="header-lightgray"/&gt; &lt;/div&gt; </code></pre> <p>So how to do it?</p> <p>Any help is appreciated.</p> <p><strong>Solution I'd like to share according to Jan Vlcinsky's answer:</strong></p> <pre><code>&lt;xsl:for-each select="/t/parent[@class='header-gray']"&gt; &lt;xsl:variable name="ns1" select="current()/following-sibling::parent"/&gt; &lt;xsl:variable name="ns2" select="current()/following-sibling::parent[@class='header-gray'][1]/preceding-sibling::parent"/&gt; &lt;div class="header-gray"&gt; &lt;xsl:for-each select="$ns1[count(.| $ns2)=count($ns2)]"&gt; &lt;span class="header-lightgray"/&gt; &lt;/xsl:for-each&gt; &lt;/div&gt; &lt;/xsl:for-each&gt; </code></pre> <p>I don't verify above code, but it's the same logic in my real code. I didn't use xslt 2.0 way because I found that lxml 2.3 I am using does not support xslt 2. </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.
