对于与此类似的多行文本:
"views_panes","gw_hero_small_site_placement-panel_pane_1",1,"a:0:{}","a:10:{s:14:\"override_title\";i:1;s:19:\"override_title_text\";s:0:\"\";s:9:\"view_mode\";s:11:\"all_purpose\";s:11:\"image_style\";s:7:\"default\";s:13:\"style_options\";a:2:{s:10:\"show_image\";i:0;s:9:\"show_date\";i:0;}s:18:\"gw_display_options\";s:22:\"gw_all_purpose_sidebar\";s:13:\"show_readmore\";a:1:{s:18:\"show_readmore_link\";i:0;}s:14:\"readmore_title\";s:9:\"Read more\";s:13:\"readmore_link\";s:0:\"\";s:7:\"exposed\";a:1:{s:23:\"field_hero_sub_type_tid\";s:3:\"547\";}}","a:0:{}","a:1:{s:8:\"settings\";N;}","a:0:{}","a:0:{}",0,"s:0:\"\";"
我正在寻找匹配的所有实例(s:)(\d{1,}:)\"(string)\";
以获得如下内容:
s:14:override_title
s:18:show_readmore_link
s:3:547
此行有或没有/g
打印仅第一个实例:
perl -nle 'print "$1 $2 $3" if /(s:)(\d{1,}:)\\"(.*?)\\";/g' tmp.txt
s:14:override_title
我想我可以尝试将它放在一个 perl 脚本中,将所有匹配项放入一个数组中,但我希望使用单行来做到这一点(-:我错过了什么?
