When migrating website content, we often encounter a tricky problem: the imported HTML content has inconsistent formats, redundant tags, and may even contain some outdated or incompatible code.This "HTML garbage" not only affects the visual consistency of the website, but may also slow down page loading speed, and even have a negative impact on search engine optimization (SEO).It is fortunate that AnQiCMS provides us with a set of efficient and flexible tools to help us batch clean up these imported HTML content.

One of the core strengths of AnQiCMS is its powerful content management functions, among which the "full-site content replacement" or the "document keyword replacement" function provided in document management is our efficient assistant for batch HTML cleaning.This feature is not limited to replacing simple keywords, it can identify and modify any text pattern we specify, including complex HTML structures, which makes it particularly important in the cleaning work after content migration.

AnQiCMS的批量清理利器：内容替换功能

The content replacement feature plays an important role in the AnQiCMS backend system.Based on our experience, it is mainly reflected in the 'Document Management' page under the 'Content Management' module.Through this feature, we can perform batch search and replace on the article content of the entire website, greatly improving the efficiency of content maintenance.It can be used whether it is for the unified label usage standard or for removing redundant inline styles.

如何使用内容替换功能进行HTML清理

To use AnQiCMS's content replacement feature to clean up the imported HTML content, you can follow the following steps:

  1. Navigate to the feature entryFirst, log in to your AnQiCMS backend.Find 'Content Management' in the left navigation bar, click to expand and select 'Document Management'.After entering the document list page, you will see an "Document Keyword Replacement" or similar batch operation entry, click on it to enter the content replacement settings interface.

  2. Configure replacement rulesIn the content replacement interface, you will see the two core input boxes “Find” and “Replace”. This is where the key cleaning rules are defined.

    • Simple text replacementFor some simple, fixed HTML code segments, direct text replacement can be performed. For example, if the old content extensively uses non-semanticized<b>Label to bold text, and you want to unify it with more semantic meaning<strong>Label, then you can input in the "Find" box<b>in the "Replace" box<strong>. Then add a rule to</b>with</strong>.

    • Using regular expressions for advanced cleaningThis is the most powerful place for content replacement in AnQiCMS.For complex and irregular HTML fragments, or for scenarios where identification and cleaning need to be performed according to specific patterns, regular expressions (Regular Expression, abbreviated as RegEx) are indispensable tools.The regular expression allows you to define complex matching patterns.<span>Label but retain the internal text, you can use similar<span>(.*?)</span>search patterns, and replace them with$1($1Represents the content within the matched parentheses).AnQiCMS supports regular expression rules, which allows you to flexibly handle various cleaning needs.It is worth noting that writing regular expressions requires certain professional knowledge.In the replacement rules description of AnQiCMS, it is also specially mentioned that incorrect regular expressions may lead to incorrect replacement effects.Therefore, make sure you have a clear understanding of regular expressions before actual operation.

  3. Execution and verificationConfigure the replacement rules first, then you can select the “Batch Replace” button to execute the operation. Since this is a site-wide or large-scale content modification, it is strongly recommended that you:

    • Backup data in advance:Before performing any batch operation, please make sure to backup your website data to prevent unexpected errors.
    • Small-scale testing:If conditions permit, you can perform replacement testing in the test environment or on a limited amount of content, and confirm the rules are correct before applying them to the entire site.
    • Check carefully:Replace completed, check some modified content to confirm that the replacement effect meets expectations.

Some practical HTML cleaning scenarios and regular expression examples

During content migration, common HTML cleaning requirements include:

  1. Remove redundant or non-semantic tags:For example, batch remove all<font>tags: Find:(<font[^>]*>|<\/font>)Replace: Leave blank (or replace with other labels as needed)

  2. Clear inline styles:Old content often contains a large amount ofstyle="..."inline styles, which can affect the unified management of CSS styles. Search:style="[^"]*"Replace: leave empty

  3. Remove empty or redundant tags:For example, remove tags with no content:<p>Tag. Search:<p[^>]*>\s*<\/p>Replace: leave empty (can also replace with a space to avoid sticking content)

  4. Unified image path or link format:If the image path or link structure changes after migration. Search:src="/old-image-path/(.*?)"Replace:src="/new-image-path/$1"(Assuming the path structure is consistent)

  5. Clean up HTML comments:查找：English<!--[\s\S]*?-->Replace: leave empty

Precautions

  • 数据备份是黄金法则：English再次强调，在进行任何批量内容修改之前，请务必进行全面的网站数据备份。English
  • 逐步测试，谨慎操作：EnglishEven if you are confident in regular expressions, it is recommended to run them on a small amount of test data first to ensure that the replacement results meet expectations before gradually expanding the scope.
  • Understand the boundaries of regular expressions:Regular expressions are very powerful, but they are also prone to 'collateral damage'. For example, a too broad rule may delete content you don't want to delete.
  • Clear cache:Batch replacement may not be immediately displayed on the front-end of the website.This is when you need to go to the "Update Cache" feature in the AnQiCMS backend, clear the system cache, and then you will be able to see the latest content effect.

Through the powerful content replacement feature provided by AnQiCMS, combined with the appropriate use of regular expressions, the HTML cleaning work after content migration will become efficient and orderly, helping your new website's content to be refreshed and providing users with a better browsing experience, as well as laying a solid foundation for the long-term operation of the website.
