Operation steps and strategies

After entering the "Document Keyword Replacement" interface, the core operation is to define the replacement rules.This feature supports two main replacement methods: normal text replacement and regular expression replacement, which is enough to meet the vast majority of content cleaning needs.

1. Perform simple text replacement

For some fixed, repetitive interference characters or HTML entities, such as 、<p> </p>Or such blank paragraphs, or specific misspellings, you can directly use text replacement.

• In the "Keyword Pair Replacement" area:
  • Enter the interfering characters or HTML entities you want to be replaced in the left input box (for example, or <p> </p>)
  • Enter the content you want to replace in the right input box. If you want to delete them directly, leave the right input box blank.
• You can add multiple replacement rules, the system will execute the replacements in the order you set.

This method is simple and straightforward, suitable for cleaning fixed text content that does not require complex matching logic.

2. Use regular expressions for advanced replacement.

When you are faced with more complex, patterned interference content, regular expressions (Regular Expression) will be your powerful weapon. For example, you may need to remove all content with specific attributes in the article.divLabel, or clear a format of contact information.

The batch replacement function of AnQiCMS supports regular expressions, and the rules need to be used{and end with}End. The document mentions some built-in commonly used rules such as{邮箱地址}/{日期}/{时间}/{电话号码}/{QQ号}/{微信号}/{网址}. You can directly use these predefined rules or write custom regular expressions according to your needs.

• Use built-in rules:
  • If you want to remove all phone numbers from the article, just enter in the left input box{电话号码}and leave the right input box blank.
• Write a custom rule:
  • For example, to remove all entries withdata-idproperties<span>tags (assuming they are noise), you can try writing something similar{<span[^>]*data-id="[^"]*"[^>]*>.*?</span>}The rule. But please note that the combination of HTML and regular expressions can sometimes be very complex.
• Use regular expressions with caution:Regular expressions are powerful but also come with risks. Improper rules may match content you do not want to modify and even damage the HTML structure of the article.It is strongly recommended to thoroughly test the rules before performing complex regular expression replacements and to validate in a non-production environment.

After completing all the settings of the replacement rules, click the 'One-click Execute' button, AnQiCMS will batch process the content of all articles on the entire site.

Implement suggestions: Ensure the practical method of content purity

1. Data backup first:Before performing any large-scale batch operations, be sure to develop the habit of backing up website data.AnQiCMS provides resource storage and backup management features, which can help you quickly recover in case of data loss or accidental operations.
2. Start testing from a small scale:If you are unsure about the effect of a replacement rule, you can first test it in a small range of articles (for example, on a test site or in a few unimportant articles) and observe whether the replacement results meet expectations.
3. Exact match, avoid injury:When setting the replacement rules, define the content you want to remove as accurately as possible.Especially when using regular expressions, fuzzy matching rules can lead to unexpected modification or deletion of normal content on your website.
