创建一个简单的解析器

问题描述

嗨.

我必须开发一个简单的解析器，以读取文本的块"
例如:

Hi.

I have to develop a simple parser, to read "block" of text
for example:

/TEST
 {. text .}
/TEST_DATA
 {. infs .}

而且，我需要阅读标签内部的信息....
和...具有此信息的文件...具有很多标签，具有相同的perfil

例如:

and, I need to read informations of inside of label....
and... the file with have this informations... have a lot of labels, with the same perfil

for example:

/TEST
 {. text .}
/TEST_DATA
 {. infs .}

/LBL1
 {. text .}
/LBL1_DATA
 {. infs .}

/LBL2
 {. text .}
/LBL2_DATA
 {. infs .}

/LBL3
 {. text .}
/LBL3_DATA
 {. infs .}

我需要阅读特殊标签块，例如:

parseFile("FileName.txt"，LBL1)

以及函数，为我返回块内部的文本:LBL1和LBL1_DATA
或者，为我返回LBL1和LBL1_DATA的内容

谢谢.

i need to read the block of specif label, for example:

parseFile("FileName.txt", LBL1)

and the function, return for me, the text of inside the blocks: LBL1 and LBL1_DATA
or, return for me, the content of LBL1 and LBL1_DATA

Thanks.

推荐答案

typedef struct
{
  char* text;
  void* data;
}DATA_INFO;

DATA_INFO& parseFile("FileName.txt", char* label )
{
  char* currentline;
  Openfile;
  getline( currentline );
  remove / from currentline; 
  comparestring( label, currentline );
  {
    DATA_INFO structinfo;
    structinfo.text = read text;
    skip line;
    structinfo.data = read data;
    return structinfo;
  } 
};

并澄清您有疑问的地方.
