解析文件并替换内容

xml2 < test.xml > test.txt
sed -i 's#/properties/entry=Mode.DEV#/properties/entry=Mode.PRO#g' test.txt

/properties/comment=

恢复为xml格式文件

echo '<?xml version="1.0" encoding="UTF-8" ?>' > test.xml
echo '<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">' >> test.xml
2xml < test.txt >> test.xml
