我很难让 XQuery 工作。我下载了 Saxon-HE 9.2。它似乎只想使用 XSLT。
当我输入：
java -jar saxon9he.jar
我得到 XSLT 的使用信息。当我对 XQuery 使用命令语法时，它无法识别参数（如 -q），并提供 XSLT 使用信息。
以下是一些命令行交互：
>java -jar saxon9he.jar

Unknown option -q:..\w3xQueryTut.xq
Saxon-HE 9.2.0.6J from Saxonica
Usage: see http://www.saxonica.com/documentation/using-xsl/commandline.html
Options:
-a Use xml-stylesheet PI, not -xsl argument
// etc...
>java net.sf.saxon.Query -q:"..\w3xQueryTut.xq"
Exception in thread "main" java.lang.NoClassDefFoundError: net/sf/saxon/Query
Caused by: java.lang.ClassNotFoundException: net.sf.saxon.Query
// etc...
Could not find the main class: net.sf.saxon.Query. Program will exit.
我可能犯了一些愚蠢的错误。你知道它可能是什么吗？
更新 1此命令不起作用：
>java -jar saxon9he.jar net.sf.saxon.Query q:"..\w3xQueryTut.xq"
Source file net.sf.saxon.Query does not exist
更新 2此命令效果更好：
>dir
