这是我过去4天一直在努力解决的问题。我阅读谷歌和SOF的教程，但没有人可以帮助我。我把它作为一个问题扔出去，以便其他人可以尝试并帮助我解决它。我已经用粗略的方法解决了它，但想想是否有更聪明的方法。所以有一个包含滚珠轴承列表及其属性的文件。它看起来像这样：

现在，如果你看一下HTML的响应（而不是html本身）。我想解析它，提取href链接中的参数（在第一个条目中，href链接中有prodid参数，prodid = 1310003030）。如果可能的话，我想在每一行的末尾追加整个链接。

我想提取它并在EACH行的末尾追加，以便条目看起来像这样。

这是sed版本。我必须承认，使用sed在不同的行上交换单词的顺序并不容易; 

sed -nre '
/^ *<a/{
    h;s/^.*prodid=([0-9]+).*$/ |\1/;x;s_^.*>([0-9]+)</a.*$_\1_
    :back
    N
    s/\n.*(Product category:).*\">(.*)<.*$/ |\1 \2/
    s_\n.*strong>(.*)</strong>(.*)$_ |\1 \2_
    /<\/li>$/ !bback
    /<\/li>$/ {
        s/<\/li>$//;G;s/\n//g;s/  */ /g;p
    }
}
' file

用于通用文本操作的UNIX工具是awk：

$ cat tst.awk
BEGIN {
    FS = "[[:space:]]*<[^>]+>[[:space:]]*"
    OFS = " |"
}

/^[[:space:]]*<a href/{
    split($0,a,/.*prodid=|&.*/)
    prodid = a[2]
    prodnr = $(NF-1)
}

/<strong>/ {
    name  = $2
    value = ($NF == "" ? $(NF-1) : $NF)
    sub(/[[:space:]]+$/,"",value)
    n2v[name] = value
    if (!seen[name]++) {
        names[++numNames] = name
    }
}

/<\/li>/ {
    printf "%s%s", prodnr, OFS
    for (nameNr=1; nameNr<=numNames; nameNr++) {
        name  = names[nameNr]
        value = n2v[name]
        printf "%s %s%s", name, value, OFS
    }
    print " " prodid
}
