This is done by simply taking each data element and writing down every tag and attribute leading up to it.

要做到这一点，只需获取每个数据元素并写下在它之前的每个标记和属性。

youdao

An index entry is created for the concatenation of the two preceding items (tag context plus data element).

为前两项(标记上下文加上数据元素)的并置创建索引项。

youdao

The data value is enclosed between the element's open tag and either the element's close tag, or the open tag for the next XML element, whichever occurs first.

数据值是元素的开始标记到元素的结束标记或 下一个 XML 元素的开始标记（以先出现的为准）之间的内容。
