Quick Start
1. Extract JSON-LD Data from HTML
from selectolax.lexbor import LexborHTMLParser
from av_ld_json_extractor import ld_json_iter
html_content = """
<!DOCTYPE html>
<html>
<head>
<script type="application/ld+json">
{"@context": "[https://schema.org](https://schema.org)", "@type": "Organization", "name": "Example Corp"}
</script>
<script type="application/ld+json">
{"@type": "Product", "name": "Gaming Laptop", "price": 1200}
</script>
</head>
</html>
"""
parser = LexborHTMLParser(html_content)
for data in ld_json_iter(parser):
print(data)
# Output:
# {'@context': '[https://schema.org](https://schema.org)', '@type': 'Organization', 'name': 'Example Corp'}
# {'@type': 'Product', 'name': 'Gaming Laptop', 'price': 1200}
2. Find Specific @type (Objects & Lists)
from selectolax.lexbor import LexborHTMLParser
from av_ld_json_extractor import find_ld_json
html_content = """
<script type="application/ld+json">
[
{"@type": "BreadcrumbList", "itemListElement": []},
{"@type": "Product", "name": "Wireless Mouse", "price": 25}
]
</script>
"""
parser = LexborHTMLParser(html_content)
# Automatically searches inside both single JSON objects and array lists
product = find_ld_json("Product", parser)
print(product)
# Output:
# {'@type': 'Product', 'name': 'Wireless Mouse', 'price': 25}
