如果有很多特殊符號不一定能處理好，需要自己調整下指令碼語言

in.txt (瀏覽器 複製元素 內容而來)

<table class="data-table"><tbody>
    <tr>
    <th>Name</th>
    <th>Description</th>
    <th>Type</th>
    <th>Default</th>
    <th>Valid Values</th>
    <th>Importance</th
 
>
    </tr>
    <tr>
    <td>blacklist</td><td>Fields to exclude. This takes precedence over the whitelist.</td><td>list</td><td>""</td><td></td><td>medium</td></tr>
    <tr>
    <td>renames</td><td
 
>Field rename mappings.</td><td>list</td><td>""</td><td>list of colon-delimited pairs, e.g. <code>foo:bar,abc:xyz</code></td><td>medium</td></tr>
    <tr>
