How to apply regular expressions in the replacement rules for security CMS keyword replacement, and what advanced techniques are there?

In the daily operation of Anqi CMS, content maintenance and optimization are the core work.Among them, the "Replace All Content" feature is undoubtedly a great tool for improving efficiency.It can not only help us unify brand information and update expired links, but also play an important role in SEO optimization.When we are faced not just with simple text replacement, but with the need to recognize and process complex, dynamic text patterns, regular expressions in replacement rules become our indispensable advanced tools.

Understanding the difference between regular replacement and regular expressions

We usually use content replacement, just like the 'Find and Replace' in Word documents: find a specific word or phrase and then replace it with another fixed word or phrase.This method is quick and efficient for tasks such as uniformly replacing the 'old company name' with the 'new company name', or replacing a fixed page URL with a new link.

However, the content of the website is often not immutable, it is filled with various dynamically generated, irregularly formatted data.For example, a website may contain various formats of phone numbers (such as 138XXXXXXXX, (010)XXXXXXXX, 400-XXX-XXXX), or embedded specific code snippets, date patterns in articles, or specific HTML tags that need to be removed.This is where the conventional text replacement falls short, as it cannot 'understand' patterns and can only perform exact matches.

The strength of AnQi CMS lies in its recognition of this need and the introduction of support for regular expressions in its 'Full Site Content Replacement' feature.This means that we are no longer limited to replacing precise strings, but can define complex matching patterns, thereby achieving more flexible and intelligent batch processing of content.

Application methods of regular expressions in security CMS

It is very intuitive to enable regular expression-based keyword replacement in the AnQi CMS. When you set the replacement rules in the "Document Keyword Replacement" or "Website Content Replacement" interface in the background, you just need to use curly braces for your regular expression pattern{}Wrap it up. The system will identify what you have entered as a regular expression based on this special marker, rather than ordinary text.

For example, if you want to match all consecutive numbers, you can use{[0-9]+}as a search pattern. Here,[0-9]
