/**
* Streaming [SAX](https://en.wikipedia.org/wiki/Simple_API_for_XML)-style HTML rewriter.
* A [transform stream](https://nodejs.org/api/stream.html#stream_class_stream_transform) (which means you can pipe _through_ it, see example).
*
* The rewriter uses the raw source representation of tokens if they are not modified by the user. Therefore, the resulting
* HTML is not affected by parser error-recovery mechanisms as in a classical parsing-serialization roundtrip.
*
* @example
*
* ```js
* const RewritingStream = require('parse5-html-rewriting-stream');
* const http = require('http');
* const fs = require('fs');
*
* const file = fs.createWriteStream('/home/google.com.html');
* const rewriter = new RewritingStream();
*
* // Replace divs with spans
* rewriter.on('startTag', startTag => {
* if (startTag.tagName === 'span') {
* startTag.tagName = 'div';
* }
*
* rewriter.emitStartTag(startTag);
* });
*
* rewriter.on('endTag', endTag => {
* if (endTag.tagName === 'span') {
* endTag.tagName = 'div';
* }
*
* rewriter.emitEndTag(endTag);
* });
*
* // Wrap all text nodes with an <i> tag
* rewriter.on('text', (_, raw) => {
* // Use the raw representation of text without HTML entities decoding
* rewriter.emitRaw(`<i>${raw}</i>`);
* });
*
* http.get('http://google.com', res => {
* // Assumes response is UTF-8.
* res.setEncoding('utf8');
* // `RewritingStream` is a `Transform` stream, which means you can pipe
* // through it.
* res.pipe(rewriter).pipe(file);
* });
* ```
