xslt如何在xml中找到我的位置?

So if I have xml that looks like the below and I am in the node "FULLTIME" how can I tell that I am in EMPLOYEE as opposed to contractor? So is there a function I can use that will return something like "ROOT/PERSON/EMPLOYEE" showing me that from the FULLTIME Node the parent nodes are ROOT, PERSON, and EMPLOYEE? I can't seem to find anything that will provide that. I am new to xslt so my ignorance is probably a big part of me not being able to find what I want.

如果我有一个看起来像下面的xml，并且我在节点“FULLTIME”中，我怎么知道我是在雇员而不是承包商呢?那么，我是否可以使用一个函数来返回诸如“ROOT/PERSON/EMPLOYEE”之类的内容，向我显示从FULLTIME节点开始，父节点是ROOT、PERSON和EMPLOYEE?我似乎找不到任何能提供这些的东西。我是xslt新手，所以我的无知很可能是我无法找到自己想要的东西的很大一部分。

<ROOT>
  <PERSON>
    <EMPLOYEE>
      <FULLTIME>
        <NAME>Mike</NAME>
        <LAST_NAME>Thompson</LAST_NAME>
        <EMPLOYEE_ID>1</EMPLOYEE_ID>
      </FULLTIME>
      <PARTTIME />
    </EMPLOYEE>
    <CONTRACTOR>
      <FULLTIME>
        <NAME>Mike</NAME>
        <LAST_NAME>Olsen</LAST_NAME>
        <EMPLOYEE_ID>2</EMPLOYEE_ID>
      </FULLTIME>
      <PARTTIME />
    </CONTRACTOR>
  </PERSON>
</ROOT>

Any suggestions would be greatly appreciated!

如有任何建议，我们将不胜感激!

The ancestor axis can be used to 'look up' through the tree. It's not entirely clear what you want to do, but you can test if EMPLOYEE is your ancestor:

祖先轴可以用来在树中“查找”。目前还不完全清楚你想做什么，但你可以测试一下员工是否是你的祖先:

<xsl:if test="ancestor::EMPLOYEE" >
   ...
</xsl:if>

#2

You could get EMPLOYEE or CONTRACTOR from FULLTIME node using name() XPath 1.0 function (or local-name() if you're utilizing namespaces):

您可以使用名称()XPath 1.0函数(或本地名称())从FULLTIME节点获得雇员或承包商(如果您正在使用名称空间):

<xsl:value-of select="name(..)"/> <!-- Returns EMPLOYEE or CONTRACTOR -->

If you want to get full absolute path like /ROOT/PERSON/EMPLOYEE, then use following recipe:

如果你想获得完整的绝对路径，比如/ROOT/PERSON/EMPLOYEE，那么使用以下方法:

<xsl:for-each select="ancestor::*">
    <xsl:text>/</xsl:text>
    <xsl:value-of select="name()"/>
</xsl:for-each>

#3

You can match EMPLOYEE/FULLTIME or CONTRACTOR/FULLTIME separately:

你可以将员工/全职或承包商/全职员工分开:

<xsl:template match="EMPLOYEE/FULLTIME">
...
</xsl:template>

<xsl:template match="CONTRACTOR/FULLTIME">
...
</xsl:template>

Then in each match you can do different things with the fulltime employees vs contractors.

然后在每一场比赛中，你可以与全职员工和承包商做不同的事情。

This is, I think, the XSLT way instead of the procedural thinking from other programming languages.

我认为，这是XSLT方法，而不是其他编程语言的过程思维。
