NSXMLParserErrorDomain 111 [英] NSXMLParserErrorDomain 111

问题描述

下面的代码是打印以下消息： Error Domain = NSXMLParserErrorDomain Code = 111无法完成操作。（NSXMLParserErrorDomain错误111。）

The code below is printing the following message: Error Domain=NSXMLParserErrorDomain Code=111 "The operation couldn’t be completed. (NSXMLParserErrorDomain error 111.)

mainUrl = [NSURL URLWithString:@"http://www.carris.pt/pt/carreiras"];
NSString *urlContents = [NSString stringWithContentsOfURL:mainUrl encoding:NSISOLatin1StringEncoding error:nil];
NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:[urlContents dataUsingEncoding:NSISOLatin1StringEncoding]];
[xmlParser parse];
NSLog(@"%@", [xmlParser parserError]);

有人有线索吗？正如您在代码中看到的那样，html采用ISO-8859-1编码。

Anybody have a clue? As you can see by the code, the html is with ISO-8859-1 encoding.

更新：我将url提交到html验证器站点： http://validator.w3.org/ 它发现了30多个错误。我认为这与错误有关。但我可以用HPPLE解析html。

Update: I submitted the url to the html validator site: http://validator.w3.org/ and it found over 30 errors. I think that has something to do with the error. But I can parse the html just fine with HPPLE.

推荐答案

似乎没有人偶然发现了正确的答案，所以现在就是这样。

Seems nobody has stumbled on the correct answer yet, so here it is.

在 NSXMLParserError文档，它说：

以下错误代码由NSXMLParser定义。对于此处未列出的错误代码，请参阅< libxml / xmlerror.h>头文件。

The following error codes are defined by NSXMLParser. For error codes not listed here, see the <libxml/xmlerror.h> header file.

未提及数字111在此列表中，我们转到 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/libxml/xmlerror .h ，并找到值：

The number 111 isn't mentioned in this list, so we go to /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/libxml/xmlerror.h, and find the value:

XML_ERR_USER_STOP, /* 111 */

libxml2中的 XML_ERR_USER_STOP 上没有很多文档，但是从阅读变更集，它看起来很快 - 解析器看到意外的EOF时失败。

There isn't a lot of documentation on XML_ERR_USER_STOP in libxml2, but from reading the changeset, it looks like it's a fast-fail when the parser sees an unexpected EOF.
