When processing HTML content collected from external sources, AnQiCMS provides a series of built-in cleaning tools and strategies, aimed at helping users efficiently manage and optimize content, ensuring the quality, security, and display effect of the website content.These features provide comprehensive support from the automated processing before content is added to the database, to the refined control during content display.

Content optimization and security filtering before archiving

When external HTML content enters the system through the 'Content Collection and Bulk Import' feature, the Anqi CMS performs multiple automatic or manual configuration cleaning processes before storing the content:

  1. Remote image localization and optimization

    • Download remote images:Many collection contents will refer to images from external servers.The Anqi CMS supports automatically downloading these remote images to the local server, which solves problems such as external image links becoming invalid and loading slowly. It also avoids the issue of images not displaying due to problems with external servers, ensuring the integrity of the content.
    • WebP format conversion and automatic compression:To further optimize website performance, Anqi CMS can be configured to automatically convert images to WebP format during image upload (including remote images downloaded after collection) and automatically compress large-sized images.This can significantly reduce the size of image files, speed up page loading, enhance user experience, and save storage space.These processes ensure that the image resources of the collected content are optimized to the maximum extent upon entry.

  2. External link filtering and processing

    • The HTML content collected often contains a large number of external links, which may have a negative impact on SEO or lead to unsafe content.The 'Whether to automatically filter external links' option is provided by AnQi CMS.If you select filtering, the system will directly remove these external links.rel="nofollow"Properties, which help indicate to search engines not to track these links, thus better controlling the flow of website SEO weight.
    • Sensitive word filtering:As part of content security management, the Anqi CMS is built with sensitive word filtering functionality.This means that when content is stored in the database, the system will automatically detect and handle (such as replacing or blocking) predefined sensitive words to ensure the compliance of the website content and reduce operational risks.

  3. Batch content replacement and correction

    • The "Full Site Content Replacement" and "Batch Article Content Replacement" features are powerful cleaning tools.Users can take advantage of these features to perform large-scale text replacement operations on the collected content.For example, remove specific ad information, standardize certain wording, correct common layout errors, and even use regular expressions to match and clear complex HTML fragments or bad style code.This is very useful for scenarios such as unifying content style, removing redundant information, and correcting format errors.

精细化控制of content rendering output

In addition to the purification before inventory, the Aiqi CMS provides a more flexible and detailed purification capability when the content is finally rendered on the webpage, through template tags and filters, ensuring the purity and safety of the front-end display:

  1. Removal and Control of HTML Tags

    • striptagsFilter:This filter can remove all HTML tags from the HTML content, leaving only plain text.This is very useful when it is necessary to extract pure text summaries from complex HTML, or to ensure that the content is displayed in the simplest form.
    • removetagsFilter:If you just want to remove specific tags (such as)<i>or<font>tags while keeping other tags),removetagsThe filter can accurately meet this requirement, allowing for the specification of one or more tags to be removed.

  2. Escaping special characters and secure display

    • escapeandeFilter:By default, the template engine of Anqi CMS automatically escapes the output HTML content, converting</>special characters to&lt;/&gt;Entities to prevent cross-site scripting (XSS) attacks.escapeandeThe filter is a tool that explicitly performs this escaping operation.
    • safeFilter:Instead, when it is determined that a segment of HTML content is safe and needs to be rendered as-is (such as content output from a rich text editor), it can be usedsafeFilter, tells the system not to escape this content.
    • escapejsFilter:For special characters in JavaScript code,escapejsThe filter can perform escaping to ensure that JS code embedded in HTML does not cause parsing errors or security issues.

  3. Correction and formatting of string content

    • replaceFilter:You can replace an old keyword with a new one before content rendering. This can be used to handle irregular text or links in collected content.
    • cutFilter:Can remove specified characters from any position in a string, which is very effective for clearing specific interfering characters or symbols from collected content.
    • addslashesFilter:Add a backslash before the predefined special characters (single quotes, double quotes, backslashes) to sanitize the string for output as a JavaScript or SQL parameter.

Through these built-in purification tools, AnQi CMS provides users with multi-level, multi-dimensional content processing capabilities. Whether it is the automated optimization at the stage of content collection and storage, or the fine control during the front-end display of content, it ensures the tidiness, security, and efficiency of the website content.
