CSS procesor

The CSS Processor is a C++ program that processes CSS code and executes specific commands to retrieve information about the CSS blocks, selectors, and attributes.
Additionally in this project I used a custom version of String built from the ground up to improve my C++ skills.

Available commands:

• ????: start command section
• ****: end command section
• ?: get number of css blocks
• i,S,?: get number of selectors in i block
• i,A,?: get number of attributes in i block
• i,S,j: get j selector from i block
• i,A,n: get from i block value for attribute n
• n,A,?: get number of blocks that contain n attribute
• z,S,?: get number of z selector occurrences
• z,E,n: get value of attribute n for selector z
• i,D,*: delete i block
• i,D,n: delete from i block attribute n

The CSS Processor takes these commands as input and provides corresponding output values for each command.

Example:

#breadcrumb  
{  
	width: 80%;  
	font-size: 9pt;  
}  

h1, body {  
	min-width: 780px;  
	margin: 0;  
	padding: 0;  
	font-family: "Trebuchet MS", "Lucida Grande", Arial;  
	font-size: 85%;  
	color: #666666;  
}  

h1, h2, h3, h4, h5, h6 {color: #0066CB;}  
????  
?  
1,S,?  
1,S,1  
1,A,?  
2,A,font-family  
h1,S,?  
color,A,?  
h1,E,color  
1,A,padding  
1,D,*  
?  
2,D,color  
?  

****  
h1, h2, h3, h4, h5, h6 {color: #0066FF;}  
????  
?  

Result:

? == 3
1,S,? == 1
1,S,1 == #breadcrumb
1,A,? == 2
2,A,font-family == "Trebuchet MS", "Lucida Grande", Arial
h1,S,? == 2
color,A,? == 2
h1,E,color == #0066CB
1,D,* == deleted
? == 2
2,D, color == deleted
? == 1
? == 2
