使用XPath Expression迭代和连接

Question

我有以下xml文件:

<author>
  <firstname>Akhilesh</firstname>
  <lastname>Singh</lastname>
</author>
<author>
  <firstname>Prassana</firstname>
  <lastname>Nagaraj</lastname>
</author>

我使用以下JXPath表达式,

concat(author/firstName," ",author/lastName)

为了获得价值Akhilesh Singh ,Prassana Nagaraj但我只是得到了Akhilesh Singh.

我的要求是我应该通过只执行一个JXPath表达式来获得两个作者的价值.

Answer 1

XPath 2.0解决方案:

/*/author/concat(firstname, ' ', lastname, following-sibling::author/string(', '))
