DevGuru XSLT unparsed-entity-uri function



			FUNCTION: unparsed-entity-uri *URI = unparsed-entity-uri('name')* The unparsed-entity-uri function returns an absolute URI (Uniform Resource Identifier) that gives access to declarations of unparsed entities in the Document Type Definition (DTD) of the source document. An entity is information that can be referenced within an XML document. There are several types of entities: external general internal parameter parsed unparsed This function only accesses unparsed entities which are declared in the DTD and generally contain binary data such as images. The empty string will be returned if the cited entity does not exist. *name* The optional name attribute is the name of an unparsed entity reference. If the provided argument is not a string, it will be converted to a string by the XPath string() function. Here is an example of an unparsed entity as it might be declared in a DTD file: <!ENTITY Guru-pix SYSTEM "guru.gif" NDATA GIF> Note that an unparsed entity cannot be referenced directly, but is referenced by name as an attribute: <GURU PIX="Guru-pix"> And would be cited in the unparsed-entity-uri function as: <img src="{unparsed-entity-uri(@PIX)}">
