#6960 new enhancement

Ignore elements for export by marker in xhtml

Description

Idea which was firstly described there (6953).

It will be useful that some html elements which marked by special marker are not exported.

For example: 

{{{
#!html
<p>
Hello <span odtexportignore>burn in hell</span>!
</p>
}}}

In odt file only "Hello !" paragraph will be.

I think it will be something like that: 

#...
html = re.sub('<([\w]+?)\s.*?\s*odtexportignore\s*>.*?</\\1>', '', html)
#...

It will be works if inside <tag></tag> are not any other elements <tag>. For general case regexp will be very interesting... :)

Another concept: 

from HTMLParser import HTMLParser

def strip(str, ignoremarker):
    class StrippingParser(HTMLParser):
        def __init__(self, ignoremarker):
            HTMLParser.__init__(self)
            self.stack = []
            self.openignores = []
            self.ignoremarker = ignoremarker
        
        def handle_data(self, data):
            if not len(self.openignores):
                self.stack.append(data)
    
        def handle_starttag(self, tag, attrs):
            if len(self.openignores):
                if self.ignoremarker in dict(attrs):
                    self.openignores.append(tag)
            elif not (self.ignoremarker in dict(attrs)):
                self.stack.append('<%s%s>' % (tag, self.__html_attrs(attrs)))
            else:
                self.openignores.append(tag)

        def handle_startend_tag(self, tag, attrs):
            if not len(self.openignores) and \
               not (self.ignoremarker in dict(attrs)):
                self.stack.append('<%s%s/>' % (tag, self.__html_attrs(attrs)))
        
        def handle_endtag(self, tag):
            if not len(self.openignores):
                self.stack.append('</%s>' % (tag))
            elif tag in self.openignores:
                self.openignores.pop()
    
        def __html_attrs(self, attrs):
            _attrs = ''
            if attrs:
                _attrs = ' %s' % (' '.join([('%s="%s"' % (k,v)) for k,v in attrs.iteritems()]))
            return _attrs
    
    stripparser = StrippingParser(ignoremarker)
    stripparser.feed(str)
    stripparser.close()
    return ''.join(stripparser.stack)

teststr = """
<html>
    <body>
        Hello<div odtexportignore> ,
                <span odtexportignore>burn in hell</span>
            </div> and be happy!
    </body>
</html>
"""

print strip(teststr, "odtexportignore")

Will work on any valid html I think.

P.S. I got some code from ​http://unethicalblogger.com/node/180
