[英]Removing starting and ending tags from a string in Perl
我有一个像这样的字符串:
<script>This String may contain other JS tags in between </script>
我的要求是从字符串中删除开始和结束Script标记,如果字符串之间有其他标记,则不应将其删除。
我如何在Perl中做到这一点?
尝试以下perl一种衬垫:
perl -lpe "s/<\/?script>//g" inputfile
在perl中:
$string =~ s!<script[^>]*>|.*</\s*script>!!g;
您可以尝试以下代码来删除开始和结束脚本标签。
"<script>This String may contain other JS tags in between </script>".replace(/^<script>|<\/script>$/g, "");
'This String may contain other JS tags in between '
要么
"foo <script>This String may contain other JS tags in between </script> foo".replace(/^((?:(?!<script>).)*)<script>(.*?)<\/script>((?:(?!<script>).)*)$/g, "$1$2$3");
'foo This String may contain other JS tags in between foo'
通过perl,
$ echo 'foo <script>This String may contain other JS tags in between </script> foo' | perl -pe 's/^((?:(?!<script>).)*)<script>(.*?)<\/script>((?:(?!<script>).)*)$/\1\2\3/g'
foo This String may contain other JS tags in between foo
在perl中,您可以进行测试以检查其是否与您的标签匹配,然后进行替换。
#!/usr/bin/perl
use warnings;
use strict;
my $string = '<script>This String may contain other JS tags in between </script>';
if ( $string =~ /^(<script>).*(<\/script>)$/ ) {
$string =~ s/$1|$2//g;
}
print $string, "\n";
这将打印:
This String may contain other JS tags in between
