How to use libtidy with tidyParseBuffer()?

I'm trying to clean some HTML with libtidy (C language), the problem is:

I want to construct a TidyDoc (a tree-like structure) with tidyParseBuffer().

I have no problem with tidyParseFile(); about tidyParseBuffer(): I'm sure I read the file properly and that the TidyBuffer structure I give to tidyParseBuffer() is correctly filled.

Any ideas?

here is the code:

    //declaration
 tidyInput = malloc(sizeof(TidyBuffer));
 tidyOutput = malloc(sizeof(TidyBuffer));
 do { 
    开发者_StackOverflow  len = fread(pbInputData, 1, nInputData, h->file);
      tidyBufAttach(tidyInput, (void*)pbInputData, len);
      tidyParseBuffer(h->doc, tidyInput);  // doc is the TidyDoc 
 } while (len >= nInputData);
 tidyOptSetBool(h->doc, TidyForceOutput, yes);

 tidySaveFile(handler->doc, "C://test.xhtml");

I did simplify the code.

The problem stems from the fact that you are trying to parse the contents of a file in chunks, reading each chunk into a buffer and calling tidyParseBuffer() for each chunk.

The tidyParseXxx() functions operate by parsing the whole input in a single call, so to do what you want you should take a look at TidyInputSource and tidyParseSource().
