序列我碰到了,指出错误中的String“的XPath失败,原因是:多个项目的顺序是不允许的包含的第一个参数()(‘字符串1’ ,'string2')“当我试图使用包含在序列中查找一个字符串。试图找到字符串使用XPath

我的代码与解决我的其他问题 https://stackoverflow.com/questions/9006479/with-pmd-and-xpath-can-i-determine-if-two-node-sets-have-any-node-in-common

Expression/PrimaryExpression/PrimaryPrefix 
[ 
contains(ancestor::ClassOrInterfaceBody/ClassOrInterfaceBodyDeclaration/FieldDeclaration/VariableDeclarator/VariableDeclaratorId/@Image,./Name/@Image) 
] 

我就遇到了这个问题,因为VariableDeclaratorId/@图片返回当有多个字段来分析两个String。我还没有找到解决方案来解决这个问题。我想过使用谓词,但这是包含谓词的内部则已,做VariableDeclaratorId/@图像[./名称/ @图片]是行不通的,因为这种[./Name/@Image]不同于PrimaryPrefix /姓名/ @图片。

预期输出:

<Expression BeginColumn="26" BeginLine="6" EndColumn="30" EndLine="6" Image="" Label=""> 
     <PrimaryExpression BeginColumn="26" BeginLine="6" EndColumn="30" EndLine="6" Image="" Label="">

的Jave来源:

public class domainFunction { 
    private int m_foo; // OK 

    public void bar() { 
     calculate (random); 
     System.out.println(m_foo); 
     System.out.println(m_two);

你好,@ttback。你没有得到答案(对于这个或你之前的问题)的原因是因为你没有写出让他们自己容易回答的问题。您应该始终提供输入XML(您已经完成)以及您要根据该输入查找的*精确*所需输出。在这里,您向我们展示了您收到的错误以及您尝试过的一些随机表达式,但是您从未告诉我们期望的输出是什么*并且*我们无法读取头脑*。 –

@lwburk:我加入了预期的输出,如果它可以更清楚。对不起,如果它不够清楚,当我发布这个时,我有点慌乱。我脑海里有很多东西。 – ttback

我认为你正在使用contains()函数是因为您错误地猜测它测试一组字符串是否包含给定的字符串。不要猜测,阅读spec:那不是contains()所做的;相反,它测试一个字符串是否包含另一个字符串。要测试一组字符串$ S是否包含字符串$ T,请使用($ S = $ T)。

谢谢。得到它解决。直到今晚我才发现这个规范。我在阅读和猜测PMD的文档方面浪费了太多时间,而没有充分考虑XPath。另外,还不清楚哪个XPath规范PMD正在使用一个点。我花了一段时间才把这些基础知识分类出来。再次感谢。 – ttback
