bleach clean在开头添加“<pre><code>”标签，而不是clean

Question

我从互联网上抓取了一些html内容，下面只是它的开始部分。

<p style="max-width: 100%;min-height: 1em;letter-spacing: 0.544px;text-align: center;box-sizing: border-box !important;word-wrap: break-word !important;"><strong style="max-width: 100%;letter-spacing: 0.544px;font-size: 24px;box-sizing: border-box !important;word-wrap: break-word !important;"><strong style="max-width: 100%;letter-spacing: 0.544px;box-sizing: border-box !important;word-wrap: break-word !important;"><span style="max-width: 100%;color: rgb(255, 41, 65);box-sizing: border-box !important;word-wrap: break-word !important;"><strong style="max-width: 100%;letter-spacing: 0.544px;color: rgb(0, 0, 0);font-size: 18px;box-sizing: border-box !important;word-wrap: break-word !important;"><span style="max-width: 100%;font-size: 24px;letter-spacing: 0.544px;box-sizing: border-box !important;word-wrap: break-word !important;"><strong style="max-width: 100%;letter-spacing: 0.544px;box-sizing: border-box !important;word-wrap: break-word !important;"><span style="max-width: 100%;letter-spacing: 0.544px;box-sizing: border-box !important;word-wrap: break-word !important;"><strong style="max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;"><strong style="max-width: 100%;letter-spacing: 0.544px;box-sizing: border-box !important;word-wrap: break-word !important;"><span style="max-width: 100%;letter-spacing: 0.544px;color: rgb(61, 167, 66);box-sizing: border-box !important;word-wrap: break-word !important;"><strong style="max-width: 100%;box-sizing: border-box !important;word-wrap: break-word !important;">...

我正在使用

body_html=bleach.clean(markdown(value, output_format='html'),tags=['SOME_ALLOWED_TAGS'] ,attributes=['SOME_ALLOWED_ATTRIBUTES'],styles=['SOME_ALLOWED_STYLES'],strip=True,strip_comments=True)

但回报并不是我所期望的，

<pre><code> &lt;p style="max-width: 100%;min-height: 1em;letter-spacing: 0.544px;text-align: center;box-sizing: border-box !important;word-wrap: break-word !important;"&gt;&lt;strong style="max-width: 100%;letter-spacing: 0.544px;font-size: 24px;box-sizing: border-box !important;word-wrap: break-word !important;"&gt;&lt;strong style="max-width: 100%;letter-spacing: 0.544px;box-sizing: border-box !important;word-wrap: break-word !important;"&gt;&lt;span style="max-width: 100%;color: rgb(255, 41, 65);box-sizing: border-box !important;word-wrap: break-word !important;"&gt;&lt;strong style="max-width: 100%;letter-spacing: 0.544px;color: rgb(0, 0, 0);font-size: 18px;box-sizing: border-box !important;word-wrap: break-word !important;"&gt;&lt;span style="max-width: 100%;font-size: 24px;letter-spacing: 0.544px;box-sizing: border-box !important;word-wrap: break-word !important;"&gt;&lt;strong style="max-width: 100%;letter-spacing: 0.544px;box-sizing: border-box !important;word-wrap: break-word !important;"&gt;&lt;span style="max-width: 100%;letter-spacing: 0.544px;box-sizing: border-box  

漂白剂干净有什么问题？是不是因为我有太多的标签和样式需要清理，所以它只是在开头添加了"<pre><code>“，并在结尾关闭了它？

Answer 1

弄清楚了。这是因为要清理的内容在开头包含\n \n\n \n\n \n \n。应该先删除它们。
