我试图找到一种选择行的方法。如果他们没有xsi命名空间，我可以做得很好，但我无法弄清楚如何用命名空间选择
以下是xsi
的内容<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:output method="html" encoding="utf-16"/>
<xsl:template match="Events">
<head>
<title>Event Log</title>
<style type="text/css">
body{ text-align: left; width: 100%; font-family: Verdana, sans-serif; }
table{ border: none; border-collapse: separate; width: 100%; }
tr.title td{ font-size: 24px; font-weight: bold; }
th{ background: #d0d0d0; font-weight: bold; font-size: 10pt; text-align: left; }
tr{ background: #eeeeee}
td, th{ font-size: 8pt; padding: 1px; border: none; }
tr.info td{}
tr.warning td{background-color:yellow;color:black}
tr.error td{background-color:red;color:black}
span {text-decoration:underline}
a:hover{text-transform:uppercase;color: #9090F0;}
</style>
</head>
<body>
<table>
<tr class="title">
<td colspan="7">Event Log</td>
</tr>
<tr>
<td colspan="2">Standard Events</td>
<td colspan="5">
<xsl:value-of select="count(//ConsoleEvent)"/>
</td>
</tr>
<tr>
<td colspan="2">Errors</td>
<td colspan="5">
<xsl:value-of select="count(//ConsoleEvent[@type='ConsoleEventError'])"/>
</td>
</tr>
<xsl:apply-templates/>

</body>
</xsl:template>
</xsl:stylesheet>
答案 0 :(得分：2)
将命名空间添加到样式表。
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
...
<xsl:value-of select="count(//ConsoleEvent[@xsi:type='ConsoleEventError'])"/>
...
答案 1 :(得分：1)
解决方案（这次记住规则！）：
将xsi namespace定义添加到您的XSLT样式表中：
相应地更改代码：
<tr>
<td colspan="2">Errors</td>
<td colspan="5">
<xsl:value-of select=
"count(//ConsoleEvent
[@type='ConsoleEventError'
or
@xsi:type='ConsoleEventError'
]
)"/>
</td>
</tr>
您的整个代码：
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
exclude-result-prefixes="xsi">
<xsl:output method="html" encoding="utf-16"/>
<xsl:template match="Events">
<head>
<title>Event Log</title>
<style type="text/css">
body{ text-align: left; width: 100%; font-family: Verdana, sans-serif; } table{ border: none; border-collapse: separate; width: 100%; } tr.title td{ font-size: 24px; font-weight: bold; } th{ background: #d0d0d0; font-weight: bold; font-size: 10pt; text-align: left; } tr{ background: #eeeeee} td, th{ font-size: 8pt; padding: 1px; border: none; } tr.info td{} tr.warning td{background-color:yellow;color:black} tr.error td{background-color:red;color:black} span {text-decoration:underline} a:hover{text-transform:uppercase;color: #9090F0;} </style>
</head>
<body>
<table>
<tr class="title">
<td colspan="7">Event Log</td>
</tr>
<tr>
<td colspan="2">Standard Events</td>
<td colspan="5">
<xsl:value-of select="count(//ConsoleEvent)"/>
</td>
</tr>
<tr>
<td colspan="2">Errors</td>
<td colspan="5">
<xsl:value-of select=
"count(//ConsoleEvent
[@type='ConsoleEventError'
or
@xsi:type='ConsoleEventError'
]
)"/>
</td>
</tr>
<xsl:apply-templates/>
</table>
</body>
</xsl:template>
</xsl:stylesheet>
并获得正确的结果：
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-16">
<title>Event Log</title><style type="text/css">
body{ text-align: left; width: 100%; font-family: Verdana, sans-serif; } table{ border: none; border-collapse: separate; width: 100%; } tr.title td{ font-size: 24px; font-weight: bold; } th{ background: #d0d0d0; font-weight: bold; font-size: 10pt; text-align: left; } tr{ background: #eeeeee} td, th{ font-size: 8pt; padding: 1px; border: none; } tr.info td{} tr.warning td{background-color:yellow;color:black} tr.error td{background-color:red;color:black} span {text-decoration:underline} a:hover{text-transform:uppercase;color: #9090F0;} </style></head>
<body>
<table>
<tr class="title">
<td colspan="7">Event Log</td>
</tr>
<tr>
<td colspan="2">Standard Events</td>
<td colspan="5">7</td>
</tr>
<tr>
<td colspan="2">Errors</td>
<td colspan="5">3</td>
</tr>
