我正试图把它变成这样的订单列表
[ [show_title_1, episode_title_1], [show_title_2, episode_title_2], ... [show_title_10, episode_title_10] ]
所以我最终可以将其打印为（例如）
社区：飞行员
被捕发展：我的母亲，汽车
我已经能够将它们分成单独的换行符分隔字符串，如下所示：
SHOW_NAMES=$("$SHOW_DATA" | grep -o 'grandparentTitle="\([^"]*\)"' | sed -e 's/grandparentTitle="//' -e 's/"//' | perl -MHTML::Entities -ne 'print decode_entities($_)'))
SHOW_TITLES=$("$SHOW_DATA" | grep -o 'title="\([^"]*\)"' | sed -e 's/title="//' -e 's/"//' | perl -MHTML::Entities -ne 'print decode_entities($_)'))
那么可以将它们转换为列表，并使用循环来构造包含这些值的嵌套列表的新列表吗？我真的在这里撞墙了。
答案 0 :(得分：0)
如果我是你，我会摆脱所有grep和sed等等，并且只依赖于模式匹配。我猜到了你想要的确切字段，但你可以根据需要轻松更新代码。我使用你的数据文件来测试，所以这将工作。该脚本采用1输入，即下载的.xml文件的文件名：
#!/bin/bash
test -r "$1" || { echo "error: invalid input, usage: ${0//*\//} filename.xml"; exit 1; }
let idx=0
while read line || test -n "$line"; do
if test "${line:0:2}" == '<V'; then
tmp=${line##* title=}
title=${tmp%% grandparentKey*}
tmp=${line##*grandparentTitle=}
gptitle=${tmp%% contentRating*}
if test "$idx" -lt "1" ; then
let idx=1
echo -n "[ [ $title, $gptitle ]"
else
echo -n ", [ $title, $gptitle ]"
fi
fi
done <"$1"
echo " ]"
exit 0
以下内容将值读入数组以允许以后处理。您可以根据需要添加其他数组，如果您愿意，甚至可以将整个文件读入数组（但是如果从磁盘上重新读取也很简单）输出与上面相同（仅用于说明） ：
let idx=0
declare -a title
declare -a gptitle
declare -a allvideo
while read line || test -n "$line"; do
if test "${line:0:2}" == '<V'; then
allvideo+=( "$line" )
tmp=${line##* title=}
title+=( "${tmp%% grandparentKey*}" )
tmp=${line##*grandparentTitle=}
gptitle+=( "${tmp%% contentRating*}" )
fi
done <"$1"
# output the original 2 variables
for ((i=0; i<${#title[@]}; i++)); do
if test "$i" -eq 0 ; then
echo -n "[ [ ${title[$i]}, ${gptitle[$i]} ]"
else
echo -n ", [ ${title[$i]}, ${gptitle[$i]} ]"
fi
done
echo " ]"
oldifs=$IFS
IFS=$'\n' # set Internal Field Separator to only break on newlines
# output the entire file with the allvideo array
for i in ${allvideo[@]}; do
echo "$i"
done
IFS=$oldifs
输出：
[ [ "Pilot", "Community" ], [ "Spanish 101", "Community" ], \
[ "Introduction to Statistics", "Community" ], [ "Home Economics", "Community" ], \
[ "Comparative Religion", "Community" ], [ "Investigative Journalism", "Community" ], \
[ "Romantic Expressionism", "Community" ], [ "Communication Studies", "Community" ], \
[ "Modern Warfare", "Community" ], [ "Advanced Criminal Law", "Community" ] ]
