xmlParseMemory的libxml2 XML_PARSE_HUGE选项 [英] libxml2 XML_PARSE_HUGE option for xmlParseMemory

问题描述

在Centos 6.4上的C ++，libxml2.x86_64 2.7.6-12.el6_4.1:

C++ on Centos 6.4, libxml2.x86_64 2.7.6-12.el6_4.1:

我正在尝试修复一个旧的C ++程序，该程序偶尔会在大型xml文件上出现XML解析器错误，似乎需要设置XML_PARSE_HUGE选项.但是我看不到任何设置它的地方！失败的代码正在使用xmlParseMemory函数，该函数仅具有2个参数-要解析的char数组及其大小.

I'm trying to fix an old C++ program that occasionally gets XML parser errors on large xml files, seems to need the XML_PARSE_HUGE option set. But I can't see any place to set it! The code that's failing is using the xmlParseMemory function which only has 2 parameters - the char array to parse and its size.

是否可以通过某种方式全局设置XML_PARSE_HUGE选项?

Is there some way to set the XML_PARSE_HUGE option globally?

推荐答案

您必须切换到

You have to switch to xmlReadMemory which has an options parameter. Simply convert calls like

xmlParseMemory(buffer, size);

到

xmlReadMemory(buffer, size, NULL, NULL, XML_PARSE_HUGE);

(我认为xmlParseMemory在解析器选项之前，并且仅保留用于向后兼容.另请参见这个问题.)

(I think xmlParseMemory predates the parser options and is only retained for backward compatibility. Also see this question.)
