[xslt] Template content problem with python?

[Norman Walsh <ndw nwalsh com>]

Ok, so I'm playing with the python interface. Here is my
'work-in-progress' xslt.py script (laugh if you must, this is my
second ever Python script :-):

#!/usr/bin/python -u

import sys
import string
import libxml2
import libxslt

# Check the arguments

usage = "Usage: %s xmlfile.xml xslfile.xsl [outputfile] [param1=val [param2=val]...]" % sys.argv[0]

xmlfile = None
xslfile = None
outfile = None
params  = {}

try:
    xmlfile = sys.argv[1]
    xslfile = sys.argv[2]
except IndexError:
    print usage;
    sys.exit(1)

try:
    outfile = sys.argv[3]
    if string.find(outfile, "=") > 0:
        name, value = string.split(outfile, "=", 2);
        params[name] = value

    count = 4;
    while (sys.argv[count]):
        try:
            name, value = string.split(sys.argv[count], "=", 2);
            if params.has_key(name):
                print "Warning: '%s' re-specified; replacing value" % name
            params[name] = value
        except ValueError:
            print "Invalid parameter specification: '" + sys.argv[count] + "'"
            print usage
            sys.exit(1);
        count = count+1;
except IndexError:
    pass

# Memory debug specific
libxml2.debugMemory(1)

nodeName = None

# ======================================================================

def f(ctx, str):
    global nodeName

    #
    # Small check to verify the context is correcly accessed
    #
    try:
        pctxt = libxslt.xpathParserContext(_obj=ctx)
        ctxt = pctxt.context()
        tctxt = ctxt.transformContext()
        nodeName = tctxt.insertNode().name
    except:
        pass

    print "called with str=" + str

    return string.upper(str)

# ======================================================================

libxslt.registerExtModuleFunction("foo", "http://example.com/foo";, f)

styledoc = libxml2.parseFile(xslfile)
style = libxslt.parseStylesheetDoc(styledoc)

doc = libxml2.parseFile(xmlfile)

result = style.applyStylesheet(doc, { "bar": "'success'" })

style.freeStylesheet()
doc.freeDoc()
result.freeDoc()

# Memory debug specific
libxslt.cleanup()
if libxml2.debugMemory(1) != 0:
    print "Memory leak %d bytes" % (libxml2.debugMemory(1))
    libxml2.dumpMemory()

If I run:

$ python xslt.py test.xml http://docbook.sf.net/release/xsl/current/html/docbook.xsl

I get:

compilation error: file /sourceforge/docbook/xsl/html/synop.xsl element text
xsltParseTemplateContent: xslt:text content problem
compilation error: file /sourceforge/docbook/xsl/html/synop.xsl element text
xsltParseTemplateContent: xslt:text content problem
compilation error: file /sourceforge/docbook/xsl/html/synop.xsl element text
xsltParseTemplateContent: xslt:text content problem
....

Running xsltproc directly doesn't produce this problem.

                                        Be seeing you,
                                          norm
