Question

假设您有这样的XML结构：

<?xml version="1.0" encoding="UTF-8" ?>

<ISExport Version="2.4" productVersion="2.4">
<ControlFlow name="CF_Order" typeId="2" >
<Variables>
   <Element paramType="LOCAL" name="$V_FromTS" datatype="TIMESTAMP" >
   </Element>
   <Element paramType="LOCAL" name="$V_ToTS" datatype="TIMESTAMP" >
   </Element>
   <Element paramType="LOCAL" name="$V_TableName" datatype="VARCHAR"     size="128" >
   </Element>
</Variables>
</ControlFlow>
<ControlFlow name="CF_Action" typeId="2" >
<Variables>
   <Element paramType="LOCAL" name="$V_FromTS" datatype="TIMESTAMP" >
   </Element>
   <Element paramType="LOCAL" name="$V_ToTS" datatype="TIMESTAMP" >
   </Element>
   <Element paramType="LOCAL" name="$V_TableName" datatype="VARCHAR"      size="128" >
   </Element>
</Variables>
</ControlFlow>
<ControlFlow name="CF_Task" typeId="2" >
<Variables>
   <Element paramType="LOCAL" name="$V_FromTS" datatype="TIMESTAMP" >
   </Element>
   <Element paramType="LOCAL" name="$V_ToTS" datatype="TIMESTAMP" >
   </Element>
   <Element paramType="LOCAL" name="$V_TableName" datatype="VARCHAR"        size="255" >
   </Element>
</Variables>
</ControlFlow>
<ControlFlow name="CF_Sales" typeId="2" >
<Variables>
   <Element paramType="LOCAL" name="$V_FromTS" datatype="TIMESTAMP" >
  </Element>
  <Element paramType="LOCAL" name="$V_ToTS" datatype="TIMESTAMP" >
  </Element>
</Variables>
</ControlFlow>
</ISExport>

我如何编写XPATH查询到

列出元素name = $V_TableName和元素size <> '128'
列出所有没有元素name = $V_TableName

我正在使用Notepad ++的XPATH插件。任何帮助表示赞赏。感谢

更新＃1，以确保我们正在测试相同元素的属性 -

//ControlFlow[Variables/Element[@name='$V_TableName' and not(@size = '128')]]/@name

试试这些

1）列出所有ControlFlow名称，其中元素名称= $ V_TableName和元素大小＆lt;＆gt; ＆＃39; 128＆＃39;

//ControlFlow[Variables/Element/@name='$V_TableName' and Variables/Element/@size != '128']/@name

2）列出所有没有Element name = $ V_TableName

的ControlFlow名称

//ControlFlow[not(Variables/Element/@name='$V_TableName')]/@name

使用XPath Query进行条件检查
