XML新手求助：XSL无法关联XML，数据无法按表格展示

问题描述 #

我是XML新手，想把客户端数据以表格形式展示。XML经验证无错误，但无法关联XSL文档，验证XSL时持续提示XML未连接。

核心问题及修正方案 #

1. 文件路径与命名 #

确保XML文件和hw3.xsl文件放在同一目录，且XSL文件名完全匹配XML中<?xml-stylesheet>指令里的href值。

2. XSL节点选择错误（关键问题） #

你的XSL里存在多处节点名称不匹配XML结构的问题：

• XML中邮箱节点是<E-mail>，XSL里误写为Email
• XML中账户总额节点是<Account_Total>，XSL里误写为Account Total
• 直接读取<Name>节点会包含换行和空白，需要拼接<First>和<Last>的值
• 表头背景色的属性值前有多余空格，会导致样式失效

3. 浏览器打开方式限制 #

部分浏览器（如Chrome）直接打开本地XML文件会因跨域限制无法加载XSL，建议：

• 使用Firefox浏览器打开
• 搭建本地HTTP服务器（如用Python的python -m http.server）后访问文件

修正后的代码 #

XML文件（无需改动，确认路径即可） #

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="hw3.xsl"?>
<!-- Simple XML file with no CSS -->
