我正在尝试编写一个XPath,它将选择包含特定单词的某些节点.在这种情况下,这个词是"洛克伍德".正确的答案是3.这两条路径都给了我3个.
count(//*[contains(./*,'Lockwood')])
count(BusinessLetter/*[contains(../*,'Lockwood')])
但是当我尝试输出每个特定节点的文本时
//*[contains(./*,'Lockwood')][1]
//*[contains(./*,'Lockwood')][2]
//*[contains(./*,'Lockwood')][3]
节点1最终包含所有文本,节点2和3为空白.
有人可以告诉我发生了什么或我做错了什么.
谢谢.
