Generate regex automatically, quickly, correctly


In many cases, the regex which we will write is not so complex and abstract, but it is too many and too long. For example, if we need to write a regex to match HTML. So, we can use this tool to generate regex quickly, simply and correctly.

In order to get and save the content which wildcard matches, we designed "Named wildcard": that is *{name:XXXX} format. But if it conflicts with your normal content, you can select another wildcard format in the front.

  2. Open HTML source code, find the corresponding HTML source. For example:
    <tr class="odd">
      <td>Name: Tom</td>
      <td>Age: 29</td>
  3. Mofidy the vary part to Wildcard: (If we want to save, use *{name:XXX} format, else use * )
    <tr *>
      <td>Name: *{name:Name}</td>
      <td>Age: *{name:Age}</td>
