The problem of tinyxml parsing UTF-8 strings

When tinyxml parses an XML file in UTF-8 format, if the file contains the following two strings: "<Name> classic document </Name>" and "<Name> News Express </Name>" fail to be resolved.

AnalysisCodeThe cause of the failure is the following code:

Function in tinyxmlparser. cpp file: const char * tixmlbase: readtext ()

 
Int Len; char Carr [4] = {0, 0, 0}; P = getchar (p, Carr, & Len, encoding); If (LEN = 1) (* Text) + = Carr [0]; // more efficientelsetext-> append (Carr, Len );
 

The preliminary analysis is to resolve the problem of UTF-8 string.

The following table is used for parsing:

Const int tixmlbase: utf8bytetable [256] = {// 0 1 2 3 4 5 6 7 8 9 a B c d e F1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, // 0x001, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1,

This table can be accessed by Google on the Internet. The reason for parsing failure is pending.
