Rapidxml parsing the value of the modified memory

1, when using rapidxml parsing, special attention, Rapidxml will modify the value of memory, the right angle brackets > modified to ' ", so pay special attention, if the char pointer to the content to use, you need to make a backup.

2, if the char pointer points to the content, no longer used, do not need to do a backup, Rapidxml will directly modify the memory. Don't forget to delete [] release resources at this time. Delete Frees memory, has no relation to the value in memory, and the value is 0, which also frees memory correctly. Using new to allocate 8 bytes of memory, the operating system allocates some more memory, and the extra memory records how much memory is allocated so that when released, you know how much memory should be freed.
