Subject: [xsl] Nested lists From: "Rick Quatro" <rick@xxxxxxxxxxxxxx> Date: Thu, 31 Oct 2013 16:22:34 -0400 |
Hi,
I have this for my input XML:
<body>
<p class="listintro">ListItem_Bullets:</p>
<p class="listitembullets">• Item 1</p>
<p class="listitembullets">• Item 2</p>
<p class="listitembullets">• Item 3</p>
<p class="normal">Paragraph within a list.</p>
<p class="listitembullets">• Item 4</p>
<p class="listitembullets">• Item 5</p>
<p class="listitemindented">• Item 1 indented</p>
<p class="listitemindented">• Item 2 indented</p>
<p class="listitembullets">• Item 6</p>
<h2>Indented list starts here:</h2>
<p class="listitemindented">• Item 1 indented</p>
<p class="listitemindented">• Item 2 indented</p>
<p class="listitemindented">• Item 3 indented</p>
<p class="normal">Paragraph within a list.</p>
<p class="listitemindented">• Item 4 indented</p>
<p class="listitemindented">• Item 5 indented</p>
<p class="listitemindented">• Item 6 indented</p>
</body>
I want to get this:
<body>
<p class="listintro">ListItem_Bullets:</p>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
<p class="normal">Paragraph within a list.</p>
<ul>
<li>Item 4</li>
<li>Item 5</li>
<ul>
<li>Item 1 indented</li>
<li>Item 2 indented</li>
</ul>
<li>Item 6</li>
</ul>
<h2>Indented list starts here:</h2>
<ul>
<li>. Item 1 indented</li>
<li>. Item 2 indented</li>
<li>. Item 3 indented</li>
</ul>
<p class="normal">Paragraph within a list.</p>
<ul>
<li>. Item 4 indented</li>
<li>. Item 5 indented</li>
<li>. Item 6 indented</li>
</ul>
</body>
I am actually getting this:
<body>
<p class="listintro">ListItem_Bullets:</p>
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ul>
<p class="normal">Paragraph within a list.</p>
<ul>
<li>Item 4</li>
<li>Item 5</li>
</ul>
<h2>Indented list starts here:</h2>
<ul>
<li>. Item 1 indented</li>
<li>. Item 2 indented</li>
<li>. Item 3 indented</li>
</ul>
<p class="normal">Paragraph within a list.</p>
<ul>
<li>. Item 4 indented</li>
<li>. Item 5 indented</li>
<li>. Item 6 indented</li>
</ul>
</body>
The problem is that I have some different list items represented by the
various class attributes. I tried to get cute with keys. It works for all of
the lists except the "listitemindented" lists. Here is my stylesheet. Any
help will be appreciated. (Forget about the bullets; I can solve that
separately.)
