如何用awk实现取两匹配行之间的行但包括第一匹配不包括第二匹配？

不加eval执行结果是：

1. paramStr        9M+7JzF+8VNrE2IAvqV2FUFMyVEsn38h6RiF2+Ue4X9yA+9xDq0lBHiCCI4gVC0cyO9XDXEL6+Wx2m0u8T5PpSrUVJ+tcNsqVU7wiqRBCEsUjfVEM9AiH8K02/HAhUeIhPirem6uuy8IT07tav4gmkV3YaJk2R6lnDwPKifC6mhQ3Pw/rAA2CC9qkK0xSsmvOl2abwaWt9cWgnc8TRSpyspj9Imr8RpsZC7tjpO2Y0hQ6MPnjEvcWzdRFapyKcqUX4nOcT8BW6tlyLGEgdEvdP0zTDv8T7FHn6wx8pnFgmN6FgLoFtTIMW+iSbc9lvVapu2eBpBlcnU2PpEt3om/N9uiLyuUOjoZyVNU83OoEoSK9jYYSr0o+Zrr32/QMoLHPQd53jNnlO4=

加了以后没报错，但看不到输出，我在前面加echo后显示的是：

有点乱了呢....

1. eval $(sed -r '/</{:1;/>/!{N};s/\n//g;/>/!b1;s/.*name="([^"]+).*value="([^"]+).*/\1=\2/}' inputfile)

复制代码

1. eval $(awk -vRS=\< -vFS=\" 'NR>1{gsub(/\n/,"");print $4"="$8}' inputfile)

复制代码

这两个是直接赋值,是没有输出的,以你的文本为例,执行之后直接

1. echo $paramStr

复制代码

就会打印出后面的字符串.

1. sed -r '/</{:1;/>/!{N};s/\n//g;/>/!b1;s/.*name="([^"]+).*value="([^"]+).*/\1\t\2/}' inputfile

复制代码

1. awk -vRS=\< -vFS=\" 'NR>1{gsub(/\n/,"");print $4"\t"$8}' inputfile

复制代码

这两个是只打印,不赋值,输出格式是:<变量名>table<变量值>

    这也行，真是一题多解，集思广益啊。
自己捉摸了一个，没有大神们的简洁：
awk '/name="paramStr" id="paramStr" value=".*/{print gensub(/.*value="([^"]+).*/,"\\1",1)}/name="paramStr" id="paramStr" value=".*/,/<input type="hidden" name="paramStrEnc" id="paramStrEnc".*/{if(i>1){print x};x=gensub(/([^"]+)" \/>/,"\\1",1);i++}' file
