我从服务器接收以下格式的数据:
I am receiving data from a server in the following format:
gin</type><sessionId>1601</sessionId><directory><default>DepthOfBook</default><study type="DepthOfBook"/
如何从该字符串中提取值 1601?我一直在尝试以下方法,但我迷失了正确的 SED 语法:
How can I extract the value 1601 from this string? I have been trying the following, but am lost with the proper SED syntax:
sed -n "/sessionId/,//sessionId/p"
sed -e "s/<sessionId/
/g"| sed -n "/sessionId/,//sessionId/p"
sed -e "s/</
/g"| sed -n "/sessionId/,/sessionId/p"
我如何提取这个值(当字符串是一个长多行字符串时,通常是两个 XML 标记之间的值)?
How can I extract this value (and generally a value between two XML tags when the string is one, long multiline string)?
谢谢.
这可能对你有用(GNU sed):
This might work for you (GNU sed):
sed '/<sessionId>/!d;s//
/;s/[^
]*
//;:a;$!{/</sessionId>/!N;//!ba};y/
/ /;s/</sessionId>/
/;P;D' file
这篇关于使用 SED 在 XML 标签之间提取值的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
