Question

我正在使用XML :: LibXML解析XML文件。对于以下XML条目，我收到错误：

Malformed UTF-8 character (fatal) at C:/Perl64/site/lib/XML/LibXML/Error.pm line 217

是

$context=~s/[^\t]/ /g;

XML中的条目如下

但我想要的东西是PMID，DateRevised，PubDate，ArticleTitle，CommentsCorrectionList和MeshHeadingList。但是，如果我删除包含其他字符的Affiliation，则此错误不再存在。我该如何解决这个错误？

Answer 1

您可以将文件转换为指定的编码（UTF-8），也可以指定实际用于文件的编码。（<?xml version="1.0" encoding="cp1252"?>）。

记事本可用于转换为UTF-8，Perl也是如此：

perl -pe"
   BEGIN {
      binmode STDIN,  ':encoding(cp1252)';
      binmode STDOUT, ':encoding(UTF-8)';
   }
" < file.cp1252 > file.UTF-8

（为了便于阅读，您必须删除我添加的换行符。）

使用XML :: LibXML解析XML时格式错误的UTF-8字符（致命）错误
