In daily website content operations, we often need to process text in various ways, such as counting the number of words in articles, controlling the display length, etc.AnQiCMS as a powerful content management system, provides us with a wealth of template filters to complete these tasks.wordcountThe filter can help us count the number of words in the text, andtrimthe filter can effectively preprocess the text, and the clever combination of the two can significantly improve the accuracy of our content statistics.

wordcountThe challenge: Hidden text boundaries

wordcountThe filter's application in AnQiCMS templates is very direct, for example,{{ archive.Content|wordcount }}It can easily count the total number of words in an article's content. Its working principle is to identify and separate words based on spaces and then count them.

However, in the actual content operation, the text we face is often not so 'clean'.Content may originate from user submissions, from other platforms collected and imported, or even from additional characters unintentionally copied and pasted by editors.wordcountThe statistics result:

  • Text at the beginning or end of a space:When a paragraph of text starts with one or more spaces, or ends with a space,wordcountIt may be misinterpreted as an additional 'empty word', which could lead to inaccurate counting. For example," Hello AnQiCMS "If such text is used directly,wordcountIt may result in an error rate higher than the actual word count.
  • Excessive newline characters and tab characters:Similar to spaces, unnecessary newlines (\n) and tab characters (\tmay also bewordcountExplained as a separator of words, thus creating non-existent 'words'.
  • Redundant spaces between words:When there are multiple spaces between two words, for example"AnQiCMS 强大",wordcountIt may identify these extra spaces as additional delimiters, which may affect the statistical results.

These subtle but widespread issues can not only lead to distortion in content word count statistics, which in turn may affect SEO strategies (such as keyword density calculation), but may also cause inconvenience in scenarios where precise text length control is required.

trimFilter: A Powerful Assistant for Text Preprocessing

Fortunately, AnQiCMS provides us withtrimFilter, which is the ideal tool to solve the above problems.trimThe core function of the filter is to remove whitespace characters such as spaces, newlines, and tabs from the beginning and end of strings.This is like a pair of scissors for trimming the edges of text, making our text neat.

trimThe basic usage of the filter is very simple:

{{ obj|trim }}

Here are theobjRepresents the string variable you need to process.trimIt will remove all whitespace characters at both ends of the string.

What's even more powerful is,trimSupports removing specific characters. If you know that the text always starts or ends with some fixed characters that you do not want to be counted, such as some punctuation or specific tags, you can specify them like this:

{{ obj|trim:"关键词" }}

However, for optimizationwordcountthe statistical results, usually using its default behavior——removing all leading and trailing whitespace is enough.

trimWithwordcountStrong Combination of

now, we cantrimFilter is related towordcountThe filter is combined and used. This process is very intuitive, you just need to.trimplace the filterwordcountbefore the filter, the text will betrimcleaned, thenwordcountcounted.

Let us feel it intuitively through an example:

{% set content_text = "   安企CMS 是一款基于Go语言开发的企业级内容管理系统   " %}

<p>原始文本词数：{{ content_text|wordcount }}</p>
<p>预处理后词数：{{ content_text|trim|wordcount }}</p>

In this example,content_textThe variable includes some extra spaces at both the beginning and the end.

  • If used directly:{{ content_text|wordcount }}The result may be,8(English, a CMS, is, a, based on Go language developed, enterprise level, content management system, ).
  • But when we use{{ content_text|trim|wordcount }}whentrimFirst, redundant spaces at both ends will be removed, making the text become"安企CMS 是一款基于Go语言开发的企业级内容管理系统".wordcountThe number of words will be counted accurately.7words.

By using this simple combination, we can ensurewordcountBased on a "clean" text for statistics, thus obtaining more accurate and reliable statistical results.
