XPATH

การค้นหาข้อมูลจากเอกสาร xml

XPath is a language for finding information in an XML document. XPath is used to navigate through elements and attributes in an XML document. XPath is a major element in the W3C's XSLT standard - and XQuery and XPointer are both built on XPath expressions. So an understanding of XPath is fundamental to a lot of advanced XML usage.
