Limitation:
-------------------------------
1. Non closed tag will be generated opened/closed without any children
2. Closed tags alone will be dealt with as Text element
3. Closed tags cannot have attribute
4. Attribute without any simple nor double quote can only contain one Digit, or onID, one tag, one jsp_element
5. Tag name cannot start with a special caracter, like <!tagName>
6. Attribute's values contained between double quote cannot contain other double quote as text
