Building + ---------------------------------------- + + Extension elements and functions as defined by XSLT 1.0 are + implemented in Sablotron since the version 0.80. Sablotron recognizes + the extension element <http://www.exslt.org/functions/script> as + suggested by exslt.org. There are some exceptions described later in + this document. Please note, that this feature is still supposed to be + EXPERIMENTAL. + + If you want to benefit form this feature, you have to install + JavaScript engine from mozilla.org (SpiderMonkey). You have to do it + even when you have Mozilla browser installed, because the binary + browser installation doesn't include essential header files. + + An alternative way to get all neccessary JS files is to download and + install Charlie application framework (see gingerall.org). + + All you need to do on Sablotron side is to run the configure script + with --enable-javascript option. To use JS engine from Charlie + installation, type: ./configure --enable-javascript --enable-perlconnect + + If you have installed JS libraries into non-standard directories, you + need to set (and export) CPLUS_INCLUDE_PATH/LIBRARY_PATH to point to + directories where the header files/lib files (e.g. libjs.so) can be found. + + The default name for the linked library is 'js' (-ljs switch) - if you + need to override this value, you may set SABLOT_JSLIB environment + variable - the configure script uses -l$(SABLOT_JSLIB) in this case. + + + 2. What is working + ---------------------------------------- + + Sablotron supports JavaScript (ECMA) scripting as described in XSTL WD + 1.1. with few exceptions: + + - DOM functions handling namespaces (with NS in their name) are not + supported (throw NOT_SUPPORTED exception) + + - DOM model is read only (as supported, may be changed later) + + - XSLTContext.stringValue is not supported + + - Document.getElementsByTagName{NS} are not supported + + - Element.getElementsByTagName{NS} are not supported + + - DTD definition nodes are not supported + + + The following summarizes what IS supported: + + - exslt:script element support + + - XSLTContext object + + - DOM2 acces to a processed document + + - type mapping between XPath and JavaScript including the XSLT + external object support + + - function-available() function + + - element-available() function + + + 3.
