Xml 用于在单个表达式中搜索多个标记的Xpath表达式

我有以下XML示例-

    <World>
    <Continents>
    <Continent>America</Continent>
    <Cities>
            <Country>USA</Country>
            <City>New York</City>
    </Cities>
    <Description>Newyork is a nice city</Description>
    <Cities>
            <Country>USA</Country>
            <City>Philadelphia</City>
    </Cities>
    <Description>Philadelphia is a nice city</Description>
    <Cities>
            <Country>USA</Country>
            <City>New Orleans</City>
    </Cities>
    <Description>New Orleans is a nice city</Description>
    </Continents>
    <Continents>
    <Continent>Asia</Continent>
    <Cities>
            <Country>India</Country>
            <City>Mumbai</City>
    </Cities>
    <Description>Mumbai is a nice city</Description>
    <Cities>
            <Country>India</Country>
            <City>New Delhi</City>
    </Cities>
    <Description>New Delhi is a nice city</Description>
    <Cities>
            <Country>India</Country>
            <City>Kolkata</City>
    </Cities>
    <Description>Kolkata is a nice city</Description>
    <Cities>
            <Country>Japan</Country>
            <City>Tokyo</City>
    </Cities>
    <Description>Tokyo is a nice city</Description>
    </Continents>
    </World>

试试下一个：

//Description[
  (preceding-sibling::Cities[1]/Country = "India" or 
   preceding-sibling::Cities[1]/City = "New York"
  ) or 
  (preceding-sibling::Continent[1] = "Asia" or 
   preceding-sibling::Cities[1]/Country = "Japan"
  )
]

我的测试中的输出（

--节点--

是我的工具添加的文本）：

纽约是个不错的城市-- 孟买是一个很好的城市-- 新德里是一个很好的城市-- 加尔各答是一个很好的城市-- 东京是个好城市

请填写您的问题标题，并向我们展示您的尝试。如果您还没有尝试过任何东西，请尝试一下。另外，请在再次发布之前阅读和。非常感谢…再次。。。我对OR和用法做了相应的更改..再次非常感谢：）答案值得损失2分

//Description[
  (preceding-sibling::Cities[1]/Country = "India" or 
   preceding-sibling::Cities[1]/City = "New York"
  ) or 
  (preceding-sibling::Continent[1] = "Asia" or 
   preceding-sibling::Cities[1]/Country = "Japan"
  )
]

<Description>Newyork is a nice city</Description>-- NODE --
<Description>Mumbai is a nice city</Description>-- NODE --
<Description>New Delhi is a nice city</Description>-- NODE --
<Description>Kolkata is a nice city</Description>-- NODE --
