What is XSLT?
什麼是XSLT？
XSLT stands for XSL Transformations
XSLT代表XSL轉換（XSL Transformations）
XSLT is the most important part of XSL
XSLT是XSL最重要的部分
XSLT transforms an XML document into another XML document
XSLT可以把XML文檔轉換成另一個XML文檔
XSLT uses XPath to navigate in XML documents
XSLT通過XPath操作XML文檔
XSLT is a W3C Recommendation
XSLT是一種W3C參考標准
XSLT = XSL Transformations
XSLT=XSL轉換（XSL Transformations）
XSLT is the most important part of XSL.
XSLT是XSL的最重要的一部分。
XSLT is used to transform an XML document into another XML document, or another type of document that is recognized by a browser, like HTML and XHTML. Normally XSLT does this by transforming each XML element into an (X)Html element.
XSLT用於把XML文件轉換成另一份XML文件，或者轉換成另一種被浏覽器所識別的諸如HTML和XHTML類型的文件。通常情況下，XSLT是通過把每個XML元素轉換成（X）Html文件來完成的。
With XSLT you can add/remove elements and attributes to or from the output file. You can also rearrange and sort elements, perform tests and make decisions about which elements to hide and display, and a lot more.
通過XSML，你可以從已輸出的文件裡添加/移除元素和屬性。你也可以把元素重新排列和分類，執行測試語句，決定是隱藏還是顯示元素，或者實現其它更多的功能。
A common way to describe the transformation process is to say that XSLT transforms an XML source-tree into an XML result-tree.
對於描述轉換過程，可以形象的描述為：XSLT把XML源樹轉（XML source-tree）換成XML結果樹（XML result-tree）。
XSLT Uses XPath
XSLT對於XPath的使用
XSLT uses XPath to find information in an XML document. XPath is used to navigate through elements and attributes in XML documents.
XSLT通過對XPath的使用來找尋XML文檔中的信息。XPath用於操作XML文件中的元素和屬性。

How Does it Work?
如何使它運行？
In the transformation process, XSLT uses XPath to define parts of the source document that should match one or more predefined templates. When a match is found, XSLT will transform the matching part of the source document into the result document.
在轉換過程中，XSLT通過XPath來定義部分應該和一個或更多預定的模板相匹配的源文件。當一個匹配找到後，XSLT將會把相匹配的部分源文件轉換成結果文檔。
XSLT is a Web Standard
XSLT是一個網絡標准
XSLT became a W3C Recommendation 16. November 1999.
XSLT在1999年11月16日成為W3C參考標准。
