3 XSLT standards define several properties about the XSLT engine itself. Querying for these properties allows to easily identify the engine.
4
5 = XSLT 1.0 =
6
7 The function [[system-property()>>http://www.w3.org/TR/xslt#function-system-property||rel="__blank"]] supports by default the following properties :
8
9 * xsl:version : a number giving the version of XSLT implemented by the processor
10 * xsl:vendor : a string identifying the vendor of the XSLT processor
11 * xsl:vendor-url : a URL identifying the vendor of the XSLT processor (typically its Web site)
12
13 The attached stylesheet [[recon-xslt10.xsl>>attach:recon-xslt10.xsl]] fingerprints a XSLT 1.0 engine.
14
15 = XSLT 2.0 =
16
17 This version supports some [[additional>>http://www.w3.org/TR/xslt20/#system-property||rel="__blank"]] properties :
18
19 * xsl:product-name : a string containing the name of the implementation, as defined by the implementer
20 * xsl:product-version : a string identifying the version of the implementation, as defined by the implementer
21 * xsl:is-schema-aware : returns "yes" if the XSLT processor is schema-aware, or "no" otherwise
22 * xsl:supports-serialization : returns "yes" if the XSLT processor offers this feature, or "no" otherwise
23 * xsl:supports-backwards-compatibility : returns "yes" if the XSLT processor offers this feature, or "no" otherwise
24
25 The attached stylesheet [[recon-xslt20.xsl>>attach:recon-xslt20.xsl]] fingerprints a XSLT 2.0 engine.
26
27 = Enumerating supported features =
28
29 == Needed functions ==
30
31 The XSLT standards define two additional functions used to enumerate the available features :
32
33 * function-available()
34 * element-available()
35
36 == Example ==
37
38 This [[stylesheet>>http://www.xmlplease.com/element-function-available.xsl||rel="__blank"]] uses these functions to test the availability of :
39
40 * XSLT and XPath functions
41
42 * XSLT elements
43
44 * Saxon extensions
45
46 * EXSLT extensions
