如何在我的Qt应用程序中简单地解析CSS（！）文件？ [英] How can I simply parse a CSS like (!) file in my Qt application?

问题描述

我有一个* .css（Cascading Style Sheets）格式的文档，但它有自己的关键字。实际上它是一个个性化的CSS（我称之为* .pss），具有自己的标签和属性。这里我有一个摘录：

I have a document in a *.css (Cascading Style Sheets) like format, but it has its own keywords. Actually it is a personalized css (I call it *.pss), with own tags and properties. here I have an excerpt:

/* CSS like style sheet file *.pss */

@include "otherStyleSheet.pss";

/* comment */
[propertyID="1230000"] { 
  fillColor : #f3f1ed;
  minSize : 5;
  lineWidth : 3;
}

/* sphere */
[propertyID="124???|123000"] { 
  lineType : dotted;
}

/* square */
[propertyID="125???"] {
  lineType : thinline;    
}

/* ring */
[propertyID="133???"] {
  lineType : thickline; 
  [hasInnerRing=true] {
    innerLineType : thinline;
  }  
}

我想解析很容易，已经有东西从Qt准备使用？

I would like to parse it very easily, is there already something Ready-To-Use from Qt? What would be the easiest way?

由于* .css有自己的关键字，所以我不会在CSS解析器中使用。

Since *.css has its own keywords, I am NOT interessted in CSS parsers.

我的进一步的意图，在解析后，* .pss是将其属性存储在模型结构。

My further intention after parsing that *.pss is to store its properties in a Model structure .

推荐答案

我知道两种可能性：

1. boost :: spirit 和在这里你可以找到一个很好的介绍boost :: spirit解析器框架


2. 我会建议写你自己的 recursive descent parser

1. boost::spirit and here you can find a good introduction to the boost::spirit parser framework
2. I would recommend to write your own recursive descent parser

* .pss不像CSS那样复杂（简单包围等），我推荐2。

Due to the fact, that your personalized *.pss is not that complex as a CSS (simple bracketing etc.), I would recommend 2.
