When working with XML data, you need to parse the data to get to the leastcommondenominator-the desired data (or atomic node value, as it is often called).
This is a least-commondenominator approach, which is at best slightly less than optimal, but more often, it is far from optimal.
这是一种最小公分母方法(least - common denominator),因为它在最好的情况下也不够理想,通常情况下,它远远不能达到最佳效果。

Knoppix can also be viewed as a "leastcommondenominator" : its purpose is to get the computer running with as little delay or human assistance as possible.
