Я столкнулся с ошибкой, в которой говорится, что «XPath не удалось из-за: Последовательность из более чем одного элемента не разрешена в качестве первого аргумента contains() ('string1' , 'string2') ", когда я пытаюсь использовать keep, чтобы найти одну строку внутри последовательности.Попытка найти строку внутри последовательности строк с XPath
Мой код связан с разрешения мой другой вопрос 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)
]
Я побежал в этом вопросе, потому что VariableDeclaratorId/@ Изображение возвращает две строки, когда есть несколько полей для синтаксического анализа. Я не нашел решения для решения этой проблемы. Я думал об использовании предикатов, но это уже содержит внутри предиката, поскольку VariableDeclaratorId/@ Image [./ Name/@ Image] не работает, потому что этот [./Name/@Image] отличается от PrimaryPrefix/Name/@Образ.

Здравствуйте, @ttback. Причина, по которой вы не получаете ответы (на этот или ваш предыдущий вопрос), заключается в том, что вы не пишете вопросы, которые поддаются легким ответам. Вы всегда должны предоставлять входной XML (который вы сделали) и * точный * желаемый вывод, который вы ищете на основе этого ввода. Здесь вы показали нам полученную вами ошибку и некоторые случайные выражения, которые вы пробовали, но вы никогда не говорили нам, что ожидаемый результат * и * мы не можем читать мысли *. –
@ lwburk: Я добавил ожидаемый результат, если он может сделать его более понятным. Извините, если он не был достаточно ясным, я был немного поспешен, когда я публиковал это. На мой взгляд, было много штук. – ttback
