每个商品标签都有内容：编码的子标签。任何人都可以建议我应该是用于检索组织名称，职称和工作ID的xpath表达式吗？
我使用过这个XPath表达式： /系统的数据结构/索引/内容/ RSS //项/内容：编码
但它给我一个错误，说“没有声明带有前缀'内容'的命名空间。”
尝试使用此表达式： substring-before（substring-after（/ system-data-structure / index / content / rss // item，“”），“”）
它检索完整的第一行为 String ='组织名称：校园娱乐'
但是我想动态地使用xpath检索组织的名称，同样用于作业标题和作业ID。
欣赏你对此的看法。
谢谢， NAV。
