我正在使用XML::Twig模块从XML文件中删除所有注释。示例文件可以是 -
<?xml version="1.0" encoding="UTF-8"?>
<Node_A>
node A content 1
<!-- One Line Comment A1-->
<![CDATA[this portion within the two comments is being
REMOVED which is not the intention]]>
<!-- Two Line Comment
Two Line Comment-->
node A content 3
<!-- Two Line Comment
Two Line Comment-->
<![CDATA[this portion within the two comments is being
REMOVED which is not the intention]]>
<!-- Two Line Comment
Two Line Comment-->
<![CDATA[
this portion is fine]]>
<Node_B> node B content
<Node_C> node c content
</Node_C>
<!-- One Line Comment -->
some data one
<!-- Multi Line Comment
Line 3Comment
1Line Comment
2Line Comment
Line 5Comment
Line Comment-->
some data again two
<!-- Multi Line Comment
Line 3Comment
Line 5Comment
Line Comment-->
few more
</Node_B>
</Node_A>
我使用的脚本如下 -
#!/usr/bin/perl
use strict;
use warnings;
use XML::Twig;
my $infile = 'demo.xml';
my $twig = XML::Twig->new (comments => 'drop', pretty_print => 'indented')->parsefile($infile);
$twig->print ();
这个脚本正在删除两个注释内部的“CDATA”部分，而这不是我的意图。 输出结果为-
<?xml version="1.0" encoding="UTF-8"?>
<Node_A>
node A content 1
<![CDATA[
this portion is fine]]><Node_B> node B content
<Node_C> node c content
</Node_C>
some data one
some data again two
few more
</Node_B></Node_A>
我需要添加什么来保留所有的CDATA部分和其他内容，只是要删除注释？
提前感谢。
