The transformation is done by an XSL processor.
转换由xsl处理器完成。
The same principle applies for the XSL processor.
同一原则适用于XSL处理器。
Usually, the extension methods are written in the same language as that of the XSL processor.
通常，扩展方法是用和XSL处理器相同的语言编写的。
As we will see, the XSL processor finds this information most easily by matching the root element.
如我们将看到的，通过匹配根元素，XSL处理器可以最轻易地找到该信息。
The result of this pre-processing is fed to an XSL processor, which generates the final XML document.
预处理的结果作为XSL 处理程序的输入，后者生成最终的XML 文档。
This XML could be dropped into another, larger XML document, displayed online, or passed into an XSL processor.
XML可以放入另外一个更大的XML文档、在线显示或者传递给XSL处理程序。
As a first step of the transformation, the XSL processor should be given a template that non-ambiguously matches some part of the source.
作为变换的第一步，应该给XSL处理器一个明确匹配源xml某一部分的模板。
Be warned, though, that FOP — Formatting Objects processor, the open-source XSL processor from Apache — does not fully implement the keep properties.
然而，需要警告的是，FOP (FormattingObjectsProcessor，格式化对象处理器)—Apache的开放源码XSL处理器—没有完全实现keep特性。
A positive note: the XSL processor cache does not need to be flushed; XSL processors with associated style sheets can be used until the style sheets change, which typically does not occur at run time.
正面评价：不必清除XSL处理器缓存。与样式表关联的XSL处理器可以一直使用到样式表改变为止，但样式表的更改一般不会在运行时发生。
