Question

我使用下面的xpath选择路径中的所有数据，一切看起来都不错，但它不会输出任何数据只有文本，并且没有错误。任何想法都错了吗？ 只是文字来克服发布的限制忽略它

concat('Which Customers dealt with which branch: ', //customers/customer/cbranch[@bid]/text())

XML

Answer 1

好吧，<cbranch/>没有text()？你有什么期望回来？

例如，如果您想要返回@bid 2

上工作的每个人的电子邮件，请使用此xpath

concat('Which Customers dealt with which branch: ', /customers/customer[cbranch/@bid = '2']/email/text())

将返回

Which Customers dealt with which branch: sammitch@hotmail.co.uk

XPATH没有显示任何数据
