XPath 绝对路径
XPath绝对路径
有两种类型的位置路径用于指定XML文档中节点的位置。这些路径是绝对路径或相对路径。
绝对路径以根节点或'/'开头。
/company/employee -它将选择类根节点内的雇员节点。
<xsl:for-each select = "/class/employee">
/company/employee？它将在类根节点内选择一个雇员节点的名字。
<p><xsl:value-of select = "/class/employee/firstname"/></p>
XPath绝对路径示例
让我们举一个使用绝对路径定位元素的示例。创建使用XPath表达式的XML文档employee.xml及其样式表文档employee.xsl。
Employee.xml
<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "employee.xsl"?>
<class>
<employee id = "001">
<firstname>Abhiram</firstname>
<lastname>Kushwaha</lastname>
<nickname>Manoj</nickname>
<salary>>15000</salary>
</employee>
<employee id = "002">
<firstname>Akash</firstname>
<lastname>Singh</lastname>
<nickname>Bunty</nickname>
<salary>25000</salary>
</employee>
<employee id = "003">
<firstname>Brijesh</firstname>
<lastname>Kaushik</lastname>
<nickname>Ballu</nickname>
<salary>20000</salary>
</employee>
<employee id = "004">
<firstname>Zoya</firstname>
<lastname>Mansoori</lastname>
<nickname>Sonam</nickname>
<salary>30000</salary>
</employee>
</class>
Employee.xsl
<?xml version = "1.0" encoding = "UTF-8"?>
<xsl:stylesheet version = "1.0">
