我想按字母顺序显示州名和国家名。如果有任何与 state 关联的county1 节点，我需要显示所有带有国家名称的州。但是，如果没有以某个字母开头的州，例如“X”，那么它不应该显示为 empty 。我很确定 xslt 可以做到这一点，但不知道如何去做。所以你们那里的大师，pleeeeeeeease帮助我。我正在使用visaul stuido2010 xml编辑器和xslt1.0 ..我无法更改xslt版本..我在这里被击中..

My Input xml Looka like below : 
     <?xml version="1.0" encoding="utf-8" ?>
        <countries>
         <country>
            <state>Ontario</state>
            <country1>CANADA</country1>
          </country>
          <country>
            <state>Swindon</state>
          </country>
          <country>
            <state>CAMDEN</state>
          </country>
          <country>
            <state>NJ</state>
            <country1>America</country1>
          </country>
          <country>
           <state>NJ</state>
            <country1>America</country1>
           </country>
          <country>
            <state>NY</state>
            <country1>America</country1>
           </country>
          <country>
             <state>DE</state>
            <country1>America</country1>
          </country>
          <country>
            <state>Queenland</state>
            <country1>Australia</country1>
          </country>
          <country>
            <state>APstate</state>
          </country>
          <country>
            <state>ANstate</state>
          </country>
        </countries>

我的输出如下所示：

  - DE
  - NJ
  - NY
ANstate
APstate
Australia
  -Queenland
C
CAMDEN
CANADA
  -Ontario
S

这为您提供了您要求的精确输出。

请注意，这是三级分组，在 XSLT 1.0 中最容易使用变量而不是使用 Muenchian 方法来完成。在 XSLT 2.0 中更容易。
