XSLT <xsl: value-of>
XSLT <xsl: value-of>元素
XSLT <xsl: value-of>元素用于提取所选节点的值。它将根据XPath表达式将所选节点的值放在文本中。
<xsl:value-of
select = Expression
disable-output-escaping = "yes" | "no">
</xsl:value-of>
参数说明
| 名称 |
说明 |
| select |
它指定要在当前上下文中求值的XPpath表达式。 |
| disable-outputescaping |
默认-"否"。如果为"是"，则输出文本将不会从文本中转义XML字符。 |
XSLT <xsl: value-of>元素示例
我们来看一个XSLT <xsl: value-of>元素及其属性"id"及其子元素<firstname>，<lastname>，<nickname>和<salary>。
Employee.xml
<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "employee.xsl"?>
<class>
<employee id = "001">
<firstname>Aryan</firstname>
<lastname>Gupta</lastname>
<nickname>Raju</nickname>
<salary>30000</salary>
</employee>
<employee id = "024">
<firstname>Sara</firstname>
<lastname>Khan</lastname>
<nickname>Zoya</nickname>
<salary>25000</salary>
</employee>
<employee id = "056">
<firstname>Peter</firstname>
<lastname>Symon</lastname>
<nickname>John</nickname>
<salary>10000</salary>
</employee>
</class>
Employee.xsl
<?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>
<h2>Employee</h2>
<table border = "1">
<tr bgcolor = "purple">
<th>ID</th>
<th>First Name</th>
<th>Last Name</th>
<th>Nick Name</th>
<th>Salary</th>
</tr>
<!--for-each processing instruction
Looks for each element matching the XPath expression
-->
<xsl:for-each select="class/employee">
<tr>
<td>
<!--value-of processing instruction
process the value of the element matching the XPath expression
-->
<xsl:value-of select = "@id"/>
</td>
<td><xsl:value-of select = "firstname"/></td>
<td><xsl:value-of select = "lastname"/></td>
<td><xsl:value-of select = "nickname"/></td>
<td><xsl:value-of select = "salary"/></td>
</tr>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>
