我想输出一个版本为20i的数据库的名称、域和使用情况。我已经创建了一个样式表来完成这项工作—当我加载xml时，它检测到表中有一个符合我的需求的元素，但实际上并不显示它们。不知道我做错了什么!

我认为你想把关于那个版本的条件放入apply-templates，并将table的创建移动到另一个模板:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h1>My Server List</h1>
<h2>Database Servers</h2>
<table border="1">
<tr>
<th>Name</th>
<th>Domain</th>
<th>Usage</th>
</tr>
<xsl:apply-templates select="Inventory/DatabaseName[Attributes[@Version='20i']]" />
</table>
<h2>Webservers</h2>
<table border="1">
<tr>
<th>Name</th>
<th>Domain</th>
<th>Usage</th>
</tr>
<xsl:apply-templates select="Inventory/WebserverName[Attributes[@Version='20i']]" />
</table>

</xsl:template>
<xsl:template match="DatabaseName">
