First of all, thanks for your help Tony
I can compile and run test, with the supplied testplugin.c there's not
problem, but when I tryed to add a function to the file i run in this error:
command:
LIBXSLT_PLUGINS_PATH=/home/gr/Plugins < "./plugin.xml" xsltproc "./plugin.xsl"
- > result.xml
error:
xmlXPathCompOpEval: function DataDetailValue not found
XPath error : Unregistered function
runtime error: file ./plugin.xsl line 11 element value-of
XPath evaluation returned no result.
where in LIBXSLT_PLUGINS_PATH is the xmlsoft_org_xslt_testplugin.so library.
Here is the cose I added:
static void getDataDetailValue(xmlXPathParserContextPtr ctxt, int nargs){
char* parameters[6] = {"novalue\n", "novalue\n", "novalue\n",
"novalue\n", "novalue\n", "novalue\n"};
char* msg = ",DataDetailValue";
int var;
for (var = 0; var < nargs; ++var) {
xmlXPathObjectPtr obj = valuePop(ctxt);
msg = concat(msg, ",");
msg = concat(msg, (char*) obj);
xmlXPathFreeObject(obj);
}
concat(msg,"\n");
parameters[0] = msg;
char* result = sendDataBySocket(parameters);
valuePush(ctxt, xmlXPathNewString(result));
}
and this is the registration of the function:
void
PLUGINPUBFUN xmlsoft_org_xslt_testplugin_init(void)
{
xsltRegisterExtModuleFull((const xmlChar *) XSLT_TESTPLUGIN_URL,
xsltExtInitTest, xsltExtShutdownTest,
xsltExtStyleInitTest,
xsltExtStyleShutdownTest);
xsltRegisterExtModuleFunction((const xmlChar *) "testplugin",
(const xmlChar *) XSLT_TESTPLUGIN_URL,
xsltExtFunctionTest);
xsltRegisterExtModuleFunction((const xmlChar *) "DataDetailValue",
(const xmlChar *) XSLT_TESTPLUGIN_URL,
getDataDetailValue);
xsltRegisterExtModuleElement((const xmlChar *) "testplugin",
(const xmlChar *) XSLT_TESTPLUGIN_URL,
xsltExtElementPreCompTest,
xsltExtElementTest);
}
I can't understand why this is not working.
Thanks for helping me
best regards
Giulio
