Simple Usage


from web_parser import HTMLParser
from web_parser.manifest import HTMLExtractionManifest
import urllib.request
import yaml

html_string = urllib.request.urlopen("https://invana.io").read().decode("utf-8")
extraction_manifest_yaml = """
- extractor_type: CustomDataExtractor
  extractor_id: content
  extractor_fields:
  - field_id: title
    element_query: 
      type: css
      value: title
    data_attribute: text
    data_type: StringField
"""
extraction_manifest = yaml.load(extraction_manifest_yaml, yaml.Loader)

manifest = HTMLExtractionManifest(
    title="invana.io blogs",
    domain="invana.io",
    version="beta",
    test_urls="https://invana.io/blogs",
    owner={

    },
    extractors=extraction_manifest

engine = HTMLParser(html_string=html_string, url="http://dummy-url.com", extraction_manifest=manifest)
data = engine.run(flatten_extractors=False)
print(data)
