Make you tired muddle-headed change direction, but still can't,"bring disaster to self, can't live" I am tired of thus of life, have however what way, so-called"life want to is a pair of scissors, you where 戳 person, where cave and convex gravamen, it would 11 what you cut tactful" really speaks very to, can I have what way.

让你累的晕头转向，但是依旧没办法，"自作孽，不可活"我厌倦了这样的生活，可是有什么办法了，所谓的"生活就想是一把剪刀，你哪儿戳人了，哪儿凹凸不平了，它会一一把你修剪的圆滑"真的讲的很对，可我有什么办法了。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
