紧急~~请各位大侠帮忙如何用awk读取部分报文

如题
已知某日志文件中有好多如下报文结构体，每个报文结构都有唯一标识TransIDO ：TransIDO20101217140042600470。
请各位大虾帮忙 用awk方法通过唯一标识TransIDO 将报文从<InterBOSS>......</InterBOSS>的内容输出！
我现在只能实现下面红色部分的输出，上边的蓝色部分不知道用awk如何输出！

<?xml version="1.0"?>

</InterBOSS>

红色部分我自己的写法是
cat T2001044-TransIDO20101217140042600470.xml | awk 'BEGIN{while(getline){if(/TransIDO20101217140042600470/) for(i=0;i<=NR;i++){ print $0; if(/InterBOSS/) break; getline;}}}' 
请各位大侠给出蓝色部分输出的方法

awk不熟，试下这个：
Assembly code

awk '/TransIDO20101217140042600470/{print "<InterBOSS>"$0}' RS="<InterBOSS>" T2001044-TransIDO20101217140042600470.xml

另外为什么非要awk？
