我一直在寻找从电子邮件正文中收到的html中提取的一些信息。在提取数据之前，我已经将html清理为仅具有最小的基本html代码＆amp;没有属性样式空行和所有。
我看到一些mailparser使用gui来选择我需要通过创建新模板来提取的字段。我还发现，如果html中有任何微小的变化，它会很聪明并像以前一样提取数据
我的问题是这些网站如何通过gui创建模板（选择我需要的文本）。还有任何开源项目或它可以帮助我的任何库。
示例：需要提取预订号，pnr，日期..首选GUI创建模板。

编辑： 目前我使用 imangazaliev / didom（PHP）创建了手动模板 指向excact节点元素来获取数据，但是对于这么多模板来说太难了，所以寻找其他模板。
