刚刚接触bat，我想在文件中aaa.xml中查找出属性<abc>，并把<abc>的值由false改成true，如果本来就是true就保留。

也在网上学习了相关的写法：
for /f "tokens=*" %%a in ('findstr /i /n "（<abc>怎么写？？）" aaa.xml‘) do （
set zf=%%a
set zf=!zf:^<abc^>=`!

for /f "tokens=1* delims=`" %%i in ("!zf!") do (
if "%%j" neq "" (
set jg=%%j
set zf=!zf:false=true!
)
)
（怎么把修改后的结果存回aaa.xml呢？）
）

新手上路，请大家多多指教，谢谢

xml的内容贴出来看看

想返回结果还是比较麻烦的

是jboss的配置文件，长我贴片段，还有特殊字符#,%,\,,.,_$
想把里面的 <attribute name="CallByValue">false</attribute> 改成true。
