使用XPath查询读取XML标签

Question

我需要通过XPath查询从我在这里报告的XML文件中推断出一系列值。

我声明我对该主题知之甚少，因此，我对技术术语的错误表示歉意。经过几次尝试，我设法获得了一些有用的数据，例如在Idc-> FileGroup-> value节点中报告的数据。与查询

//m:meta[2]/@value

根据索引1、2、3等返回TAGs“值”的不同值。

尽管进行了多次尝试，但是我无法创建一个查询，该查询允许我获取以下TAG的值：Idc-> FileGroup-> File s：format-> Path

对应于docs/002678E3.pdf，来自TAG

IdC-> SelfDescription-ID s;

方案，对应于

1520038843024

或者对我来说一样，

"local">1520038843024

您能给我帮助吗？这是我的XML：
