如何在<xml：choose>？</xml：choose>中包装一组项目

时间：2010-07-12 21:52:46

标签： xslt

<div>不能是<xml:choose>的孩子，但我只想重复<li>次 - 换句话说，不是他们的父<div>或{{1} }}第

下面你会找到我的样本输入，XSLT和样本所需的输出。

输入

<ul>

XSLT 

<?xml version="1.0" encoding="utf-8" ?>
    <Collection>
      <Content>
        <Html>
          <root>
            <news>
              <title>Item 1</title>
              <publication-date>2010-04-16</publication-date>
              <article-content>
                <p>Aliquam mollis porttitor auctor. Aenean laoreet justo sed ipsum lobortis eleifend. In ac mollis neque. Donec rutrum turpis vel quam mattis eu vestibulum arcu tincidunt.</p>
              </article-content>
            </news>
          </root>
        </Html>
      </Content>
      <Content>

            </news>
          </root>
        </Html>

你的结构错了。这是一个语法上有效（但未经测试）的重构。我没有测试，因为你没有发布一些输入XML，但我认为这就是你想要的。

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

注意：这样您就可以获得所需内容。在您的模板中“模式匹配”您的输入，您可以更好地表达您想要的输出并增加可重用性和维护的可能性。

修改：稍加改动以强调“模式匹配”。
