anywhere in a tag, for example xsl:value-of.select and xsl:variable.name. name() the name of the tag being processed. Useful if the matching criteria contains |s (pipe symbols). any conditional or match criterion, for example xsl:if.test, xsl:when.test, xsl:template.select and xsl:for-each.select. @ an attribute within the XML.
In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference.
The XSLT 1.0 recommendation recommends the more general attribute types text/xml and application/xml since for a long time there was no registered media type for XSLT. During this time text/xsl became the de facto standard.
contains(string,substring) returns boolean Description Returns whether string contains substring as a substring. This is equivalent to using Find and then detecting that it does not result in the failure condition listed in the third column of the Find section. However, some languages have a simpler way of expressing this test. Related
XSL-FO (XSL Formatting Objects) is a markup language for XML document formatting that is most often used to generate PDF files. XSL-FO is part of XSL (Extensible Stylesheet Language), a set of W3C technologies designed for the transformation and formatting of XML data.
In both cases the key can take the form of an attribute, element, or computed value. The unique identifier is referred to as a key because of the use of the 'key' function to identify and track the group variable. The technique is not necessary in XSLT 2.0+, which introduces the new for-each-group tag.
In C#, any variable names may be prefixed with "@". This is mainly used to allow the use of variable names that would otherwise conflict with keywords. [9] The same is achieved in VB.Net by enclosing the name in square brackets, as in [end]. [10] The "@" prefix can also be applied to string literals; see literal affixes below.
XQuery (XML Query) is a query and functional programming language that queries and transforms collections of structured and unstructured data, usually in the form of XML, text and with vendor-specific extensions for other data formats (JSON, binary, etc.).
