XMLReader编码错误 [英] XMLReader encoding error

问题描述

我有一个PHP脚本正在尝试解析巨大的XML文件.为此，我使用XMLReader库.在解析期间，我遇到了此编码错误:

I have a PHP script which is trying to parse a huge XML file. To do this I'm using the XMLReader library. During the parsing, I have this encoding error:

输入不正确的UTF-8，请指示编码！字节:0xA0 0x32 0x36 0x30

Input is not proper UTF-8, indicate encoding ! Bytes: 0xA0 0x32 0x36 0x30

我想知道它们是否是一种跳过带有不良字符的记录的方法.

I would like to know if they are a way to skip records with bad characters.

谢谢！

推荐答案

首先，请确保您的XML文件确实是UTF-8编码的.如果未将编码指定为 XMLReader :: open() .

First of all, make sure that your XML file is indeed UTF-8 encoded. If not specify the encoding as the second parameter to XMLReader::open().

如果编码错误是由于UTF-8文档中的字节序列格式错误，并且您使用的是PHP> 5.2.0，则可以传递 LIBXML_NOERROR 和/或(取决于错误级别) LIBXML_NOWARNING 作为第三个参数的位掩码> XMLReader :: open() :

If the encoding error is due a real malformed byte sequence in an UTF-8 document and if you're using PHP > 5.2.0 you could pass LIBXML_NOERROR and/or (depending on the error level) LIBXML_NOWARNING as a bitmask to the third parameter of XMLReader::open():

$xml = new XMLReader(); 
$xml->open('myxml.xml', null, LIBXML_NOERROR | LIBXML_NOWARNING); 

如果您使用的是PHP> 5.1.0，则可以调整 libXML 错误处理.

If your're using PHP > 5.1.0 you can tweak the libXML error-handling.

// enable user error handling
libxml_use_internal_errors(true);
/* ... do your XML processing ... */
$errors = libxml_get_errors();
foreach ($errors as $error) {
    // handle errors here
}
libxml_clear_errors();

我实际上不知道前面的两个变通办法是否真的允许 XMLReader 在出现错误的情况下继续读取，或者它们是否仅抑制错误输出.但这值得一试.

I actually don't know if the preceding two work-arounds actually allow XMLReader to continue reading in case of an error or if they only suppress the error output. But it's worth a try.

回复评论:

libXML 定义 XML_PARSE_RECOVER (1)，但ext/libxml并未将此常量公开为PHP常量.也许可以将整数值 1 传递给 $ options 参数.

$xml = new XMLReader(); 
$xml->open('myxml.xml', null, LIBXML_NOERROR | LIBXML_NOWARNING | 1);
