畸形的UTF-8字符（致命）的错误，而使用XML解析XML ::的libxml(Malformed

我解析使用XML XML文件::的libxml。 对于下面的XML条目我得到的错误：

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

这是

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

在XML中的条目是以下

但我想从这个入口的东西是PMID，DateRevised，pubdate的，ArticleTitle，CommentsCorrectionList和MeshHeadingList。 但是，如果我删除所属里面包含了一些其他的字符，该错误是没有更多的。 我应该怎么解决这个问题？

Answer 1:

您既可以将文件转换为指定的编码（UTF-8），或者你可以指定实际使用的文件的编码。 （ <?xml version="1.0" encoding="cp1252"?> ）。

记事本可以用来转换为UTF-8，所以可以使用Perl：

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

（你必须去掉换行符我增加了可读性。）
