求救:从文本中提取信息的shell函数实现过程

hfvbc

需求:
现有文本test.txt
内容为:
         Connection><DataSource modified='1' type='string'><![CDATA[xdatasourcex]]></DataSource><Username modified='1' type='string'><![CDATA[xusernamex]]></Username><Password modified='1' type='protectedstring'><![CDATA[xpasswordx]]></Password></Connection><Usage><WriteMode type='int'><![CDATA[xwritemodex]]></WriteMode><GenerateSQL modified='1' type='bool'><![CDATA[xgene is wom ratesqlx]]></GenerateSQL><TableName modified='1' type='string'><![CDATA[xtablenamex]]></TableName>

我想写一个函数getinfo,实现的功能如下:
getinfo DataSource test.txt得到的输出为xdatasourcex
getinfo Username test.txt得到的输出为xusernamex
getinfo GenerateSQL test.txt得到的输出为xgene is wom ratesqlx

awk -F $1 '{print $2}' tmp.txt|cut -f 3 -d [ | cut -f 1 -d ]>test.txt

谢谢大侠,完全正确,佩服佩服.
我的这个
#!/bin/sh
fin=$1
fn=$2
awk 'BEGIN{FS="'$fin'"}{print $2}' ${fn}|awk -F'[' '{print $3}'|awk -F']' '{print$1}'
不能用.
