试试这个XPath：

//OrderLine[.//ProductType[text()='EMAIL']]

这是非常相似的地方表达。

您搜索所有//OrderLine，特殊条件。在你的情况下，这个条件是里面的某个地方应该是productType，所以它的"//ProductType[text()='EMAIL']"。在它之前还应该添加一个点.，以通过OrderLine中的相对xpath搜索产品类型，而不是xml文件中的某处。

这适用于选择一个具有文本“EMAIL”的元素（第一个元素），但不适用于包含文本的所有元素。 –

此xpath将查找满足条件的所有元素。问题是你用什么工具来搜索它。可能你应该使用类似“findAll”等的东西 –

只要把条件为方括号：

/InputOrder/Order/OrderLine[Product/Email/ProductType="EMAIL"]

它被称为谓词 XPath中。
