# FRXML : Fast/Robust XML parser

FRXML is DOM-based light-weight & robust XML parser, written in C++17 - with a goal

that is to archive `O(n)` level of memory occupancy,

regardless of how deep the depth of the xml document is

## Benchmark

![benchmark](Figure_1.png)

* lower is better

## Features

- zero-copy/single-pass parsing

- UTF-8 supported (without BOM)

- limited XML 1.0

## Limitation

- No `` things such as `' content '' name '>'

empty_element ::= '<' name (S attr)* S? '/>'

      comment ::= ''

      pcinstr ::= '' name (S (CHAR* - (CHAR* '?>' CHAR*)))? '?>'

      

content ::= node (S? content)?

```

## Usage

### Parsing

```c++

#include 

#include 

int main()

{

    std::string xml = R"(

    <유니코드 attr="안녕하세요" attr0="1">

    유니코드>

    

    

)";

    frxml::doc doc{ xml };

    if (!doc)

    {

        std::cout << std::to_string(error.exception()) << '\n';

    }

}

```
