Hi everyone,  
I have a log file generated by LogWriter and it is separater by tags, loike this  
`@@@20190708093430179@@@AppName@@@getListNotify@@@<vas:Input>#@n@##@t@#<username>foo</username>#@n@##@t@#<password>oof</password>`  
Can I use logstash to automatically splits the content inside the tags into fields, and which filter do I use?  
Thanks
