Wrap a text node in to current or parent node

[raylua2566]

Feature: Wrap a text node in to current or parent node 新特征: 封装一个纯文本到一个当前或者父节点里 TODO:  ... et. not handle yet, create a ElementNode function to handle them? TODO: 一些特殊字符还没有处理, 考虑创建一个ElementNode实例方法处理特殊字符?

Could you, please: 1) describe the use-case for this? 2) provide a test code, that will show this usecase (and so fail on current master, but will work after your PR)? 3) strip Chinese comments (keeping only english ones)?

Well, 3rd one is pretty cosmetic and have no consequences on how library works, but I'm asking about first two, because I am missing the end purpose (real-world example, when it would be useful) of that changes.

Please forgive my grammar mistakes.

From README.md

Limitations

• Textnodes are no separate tree elements; in local root = htmlparser.parse("<p>line1<br />line2</p>"), root.nodes[1]:getcontent() is "line1<br />line2", while root.nodes[1].nodes[1].name is "br"

Now

• My PR will wrap the Text line1 and line2 into a node named text, after that while root.nodes[1].nodes[1].name is "text", and #root.nodes[1].nodes is 3

real-world example, when it would be useful

• xpath has a func text() to get literals text . Do not you want it?
• Get ordered tags within a a tag contains <text> and <img>.

Why test case failed?

• Test case file "tst/init.lua" that function test_order() case will not true at line 292, because the text 1 performance for <text>1</text> implicitly, the same as texts 2 3 ...10. so the :not(n)'s result is 14 instead of 4 Discussion
• the origin str contains <text>some text</text> ^_^

Ping?

Sorry for long disappearing, I was having a lot of personal issues :-/

Let's discuss further implementation of that idea?

I'll close it for now, since it is incomptible with current code base now.

If you (or someby else) want to continue work on that - feel free to open new PR.
