了解XSLT中的XPath [英] Understanding XPath in XSLT
问题描述
全部，
我是XSLT的新手，在理解
XPath的语法时遇到一些问题，它选择了XML文档中的节点。考虑一下
XML，它包含三个外部XML元素。
< FOO> foo.top.level< / FOO>
< BOO>< FOO> foo.second.level< / FOO>< / BOO>
< CHOO>< BOO>< FOO> foo.third。等级< / FOO>< / BOO>< / CHOO>
我的测试显示
（a）" / * / FOO"导致空字符串
（b）" // FOO"结果为foo.top.level
（c）" / FOO"导致空字符串
（d）" // * / FOO"结果为foo.top.level
（e）" // * / * / FOO"结果为foo.top.level
（f）" // BOO / FOO"结果是foo.second.level
我正在接受这样的结果...
< xsl ：variable name =" foo1" select =" / * / FOO" />
我为什么各种XPath选择各种节点而感到绝望。
非常感谢您提供的任何帮助。
谢谢，

All,
I am new to XSLT and having some problems understanding the syntax of
XPath which selects nodes in the XML document. Consider this bit of
XML, which contains three outer XML elements.
<FOO>foo.top.level</FOO>
<BOO><FOO>foo.second.level</FOO></BOO>
<CHOO><BOO><FOO>foo.third.level</FOO></BOO></CHOO>
My testing shows
(a) "/*/FOO" results in a empty string
(b) "//FOO" results in "foo.top.level"
(c) "/FOO" results in a empty string
(d) "//*/FOO" results in "foo.top.level"
(e) "//*/*/FOO" results in "foo.top.level"
(f) "//BOO/FOO" results in "foo.second.level"
I''m picking up the results like this...
<xsl:variable name="foo1" select="/*/FOO"/>
I''m hopelessly confused as to why various XPath''s pick various nodes.
Any help you can provide is greatly appreciated.
Thanks,
TFSquare

XML文档不能包含三个外部元素，所以我是惊讶
你没有收到错误。你究竟在做什么？

An XML document can''t contain three outer elements, so I''m surprised
you''re not getting an error. What exactly are you doing?
