我正在尝试为我的Android项目使用webview创建epub阅读器中的“高亮显示器”。 我正在使用Rangy获取选定文本。 在从下面示例HTML选择文本后,序列化函数会给我返回此值:
2/5/3/5/1/2:0,13/5/3/5/1/2:24
我将这个存储在数据库中。当用户返回到这个页面时,我会检索相同的选择并尝试反序列化,但是反序列化函数会抛出以下错误:
Error in Rangy Serializer module: deserializePosition failed: node <DIV>[7] has no child with index 13, 0
我不明白为什么会发生这种情况?即使我尝试使用XPath做同样的事情,问题依然存在。

In human beings, height, colour of eyes, complexion, chin, etc. are
some recognisable features. A feature that can be recognised is known as
character or trait. Human beings reproduce through sexual reproduction. In this
process, two individuals one male and another female are involved. Male produces
male gamete or sperm and female produces female gamete or ovum. These gametes fuse
to form zygote which develops into a new young one which resembles to their parent.
During the process of sexual reproduction
