このデータを抽出する良い方法は何ですか?
答え1
これはXMLstarletを使用して行われ、paste
おそらくXMLstarletを一度呼び出すことで実行できますが、私はウィザードではありません。
$ paste <(xml sel -T -t -v '//@estimated' data.xml) \
<(xml sel -T -t -v '//@fullSign' data.xml)
1469138452000 MAX Blue Line to Hillsboro
1469138664000 MAX Red Line to City Center & Beaverton
1469139140000 MAX Blue Line to Hillsboro
1469139577000 MAX Red Line to City Center & Beaverton
答え2
$ xml2 < sunnx.xml | awk -F= '
$1 ~ /@fullSign/ { fs=$2 ; sub(/&/,"&",fs) };
$1 ~ /@estimated/ { est=$2 };
fs && est { printf "%s %s\n", est, fs; fs=est="" }'

&
代わりにリテラルが必要な場合は、関数呼び出しを &
削除してください。エンコードされたエンティティをデコードするため、要求に合わせて再度変更する出力を追加しました。sub()
xml2
sub()
それ以外の場合、sub()
出力は次のようになります。
1469138452000 MAX Blue Line to Hillsboro
1469138664000 MAX Red Line to City Center & Beaverton
