Bug: wrong comment tokenizing

[abiriadev]

The approach this library uses is totally wrong.

ts-xml-parser/src/parser.ts

Lines 38 to 40 in b7e21b3

	// 去掉两端空格和注释
	xml = xml.trim()
	xml = xml.replace(/<!--[\s\S]*?-->/g, "")

For a minimal test case like below,

<a attr="<!--not a comment-->"></a>

The expected result is

{ name: "a", attributes: { attr: "<!--not a comment-->" } }

However, the actual result is

{ name: "a", attributes: { attr: "" } }
