Ajax - Developer guides
xpath xpath stands for xml path language, it uses a non-xml syntax that provides a flexible way of addressing (pointing to) different parts of an xml document.

Parsing and serializing XML - Developer guides
xpath a technology for creating strings that contain addresses for specific portions of an xml document, and locating xml nodes based on those addresses.

eval() - JavaScript
pass data instead of code for example, an extension designed to scrape contents of web-pages could have the scraping rules defined in xpath instead of javascript code.

<xsl:decimal-format> - XSLT: Extensible Stylesheet Language Transformations
xslt/xpath reference: xslt elements, exslt functions, xpath functions, xpath axes the <xsl:decimal-format> element defines the characters and symbols that are to be used in converting numbers into strings using theformat-number( ) function.

<xsl:element> - XSLT: Extensible Stylesheet Language Transformations
xslt/xpath reference: xslt elements, exslt functions, xpath functions, xpath axes the <xsl:element> element creates an element in the output document.

<xsl:fallback> - XSLT: Extensible Stylesheet Language Transformations
xslt/xpath reference: xslt elements, exslt functions, xpath functions, xpath axes the <xsl:fallback> element specifies what template to use if a given extension (or, eventually, newer version) element is not supported.

<xsl:import> - XSLT: Extensible Stylesheet Language Transformations
xslt/xpath reference: xslt elements, exslt functions, xpath functions, xpath axes the <xsl:import> element is a top-level element that serves to import the contents of one stylesheet into another stylesheet.

<xsl:include> - XSLT: Extensible Stylesheet Language Transformations

<xsl:message> - XSLT: Extensible Stylesheet Language Transformations
xslt/xpath reference: xslt elements, exslt functions, xpath functions, xpath axes the <xsl:message> element outputs a message (to the javascript console in ns) and optionally terminates execution of the stylesheet.

<xsl:namespace-alias> - XSLT: Extensible Stylesheet Language Transformations
xslt/xpath reference: xslt elements, exslt functions, xpath functions, xpath axes the <xsl:namespace-alias> element is a rarely used device that maps a namespace in the stylesheet to a different namespace in the output tree.

<xsl:otherwise> - XSLT: Extensible Stylesheet Language Transformations
