我有一個包含電影信息的XML文件。我希望我的表達能夠返回指向多個電影的XML中的導演。XML:返回滿足給定條件的序列元素
我現在擁有的是:
for $director in //director
where count($director) > 1
return $director
這不會產生任何東西。我正在試圖做的是:
對於在XML每名董事: 回報導演的名字,如果導演的名字被命名爲比//主任
你將如何解決這個問題再一次?

如果您想列出擁有多部電影的導演,請務必提供一個實際適用於您的問題的示例:我會建議至少有三部電影,兩部使用相同的導演,另一部使用另一部,所以有兩個導演匹配,而那些導演不匹配。與此同時,您可以省略大部分其他不相關的標籤。 –
而且不要發佈[完全相同的問題多次](http://stackoverflow.com/questions/32924082/xml-return-elements-of-a-sequence-that-occur-certain-number-of-times )。 –
