下面是xml文件

<config>
	<web>
		<host>172.16.6.70</host>
		<port>5055</port>
	</web>
	<db>
		<host>172.16.6.78</host>
		<port>5432</port>
		<username>postgres</username>
		<password>postgres</password>
		<dbname>RemoteAssert</dbname>
	</db>
	<sftp>
		<host>172.16.6.78</host>
		<username>root</username>
		<password>*********</password>
		<remote>/opt</remote>
		<local>/home/liujiayu/diagnosefile/cmdanddatafile</local>
	</sftp>
	<path>
		<result>/home/liujiayu/diagnosefile/result</result>
		<report>/home/liujiayu/diagnosefile/report</report>
	</path>
	<multipack>
		<timeout>10</timeout>
		<maxcount>3</maxcount>
	</multipack>
	<singlepack>
