比较简易待后续优化目前只是短时间批量转换html文件。
const { JSDOM } require(jsdom);const getText (htmlString) {if (!htmlString) return ;if (typeof (htmlString) ! string) {htmlString htmlString.textContent;}return htmlString.replaceAll(/\s/g, );
}
const format {h1: (element) {return \n# ${getText(element)}\n;},h2: (element) {return \n## ${getText(element)}\n;},h3: (element) {return \n### ${getText(element)}\n;},h4: (element) {return \n#### ${getText(element)}\n;},h5: (element) {return \n##### ${getText(element)}\n;},h6: (element) {return \n###### ${getText(element)}\n;},code: (element) {let className element.getAttribute(class) || ;className className.replace(language-, );return \n className \n element.textContent \n\n;},blockquote: (element) {let resultreformat(element);let arrresult.split(\n\n);return arr.join( );},p: (element) {return \n${getText(reformat(element))}\n;},strong: (element) {return **${getText(element)}**},a: (element) {return [${getText(element)}](${element.getAttribute(href)})},s: (element) {return ~~${getText(element)}~~},em: (element) {return *${getText(element)}*},img: (element) {return });},ol: (element) {let result \n;let index 1;for (let child of element.childNodes) {if (child.tagName child.tagName.toLowerCase() li) {result ${index}. ${getText(child)}\n;}}return result;},ul: (element) {let result \n;for (let child of element.childNodes) {if (child.tagName child.tagName.toLowerCase() li) {result - ${getText(child)}\n;}}return result;},table: (element) {let result \n;let row 0;const getTRString (tr) {let str |;if (tr) {for (let td of tr.childNodes) {if (td.tagName td.tagName.toLowerCase() td) {str getText(td) |}}}if (str.length 1) str | |return str \n;}for (let child of element.childNodes) {if (child.tagName) {for (let tr of child.childNodes) {if (tr.tagName tr.tagName.toLowerCase() tr) {result getTRString(tr);row;if (row 1) {//这个是markdown识别表格的标识 |---|---|--|----|--| 一般情况下宽度会自适应result |for (let td of tr.childNodes) {if (td.tagName td.tagName.toLowerCase() td) {result ---|;}}result \n;}}}}}return result;}
}
//二次格式化如pstrong123/strong/p 第一次格式化只会匹配到p因此需要二次格式化处理内在元素
const reformat (element) {let result ;for (let child of element.childNodes) {if (child.tagName format[child.tagName.toLowerCase()]) {//拦截命中result format[child.tagName.toLowerCase()](child);} else {//没有需要处理的标签深入处理result getText(child.textContent);}}return result;
}
const dp (element) {let markdownStringArray [];for (let child of element.childNodes) {if (child.tagName) {let functionName child.tagName.toLowerCase();//取出标签名称if (format[functionName]) {//拦截命中markdownStringArray.push(format[functionName](child));} else {//没有需要处理的标签深入处理markdownStringArray markdownStringArray.concat(dp(child));}}}return markdownStringArray;
}exports.html_to_markdown (htmlString) {const dom new JSDOM(htmlString);const body dom.window.document.body;let arr dp(body);return arr.join();
}
使用方法
const markdownString html_to_markdown(html);
