/**
 * 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);
 * });
 * ```
