A basic usage example is remarkably similar to Python's HTMLParser:

from HtmlTemplateParser import Htp
from HtmlTemplateParser import AttributeParser


class MyAttributeParser(AttributeParser):
    def handle_starttag_curly_perc(self, tag, attrs, props):
        print("starttag_curly_perc", tag, attrs, props)

        # get the position of the element relative to the original html
        print(self.getpos())

        # get the original html text
        print(self.get_element_text())

    def handle_endtag_curly_perc(self, tag, attrs, props):
        print("endtag_curly_perc", tag, attrs, props)

    def handle_value(self, value):
        print("value", value)


class MyHTMLParser(Htp):
    def handle_starttag(self, tag, attrs):
        print("Encountered a start tag:", tag)
        print(self.getpos())

        MyAttributeParser(attrs).parse()

    def handle_endtag(self, tag):
        print("Encountered an end tag :", tag)

    def handle_data(self, data):
        print("Encountered some data  :", data)

parser = MyHTMLParser()
parser.feed('<html><head><title>Test</title></head>'
            '<body {% if this %}ok{% endif %}><h1>Parse me!</h1></body></html>')
