legendtkl PDF to XML Conversion Guide
Overview
This skill enables the conversion of PDF files into XML format, facilitating structured data extraction and manipulation. This feature is particularly useful for applications that require data processing and integration with XML-based systems.
Conversion Process
The conversion process involves reading a PDF document and generating an equivalent XML representation, maintaining the document's structure and contents.
Quick Start
from pypdf import PdfReader
import xml.etree.ElementTree as ET
# Function to convert PDF to XML
def pdf_to_xml(pdf_file, xml_file):
reader = PdfReader(pdf_file)
root = ET.Element("document")
for page in reader.pages:
page_element = ET.SubElement(root, "page")
page_element.text = page.extract_text()
tree = ET.ElementTree(root)
tree.write(xml_file)
# Convert PDF to XML
pdf_to_xml("input.pdf", "output.xml")
Handling Complex PDF Structures
For PDFs that contain images, tables, or special formatting, additional handling may be required:
# Convert PDF with special handling
from pypdf import PdfReader
from your_image_extraction_library import extract_images
def convert_complex_pdf(pdf_file, xml_file):
reader = PdfReader(pdf_file)
root = ET.Element("document")
for i, page in enumerate(reader.pages):
page_element = ET.SubElement(root, "page")
page_element.text = page.extract_text()
# Extract images and append to XML
images = extract_images(page)
for img in images:
img_element = ET.SubElement(page_element, "image")
img_element.text = img
tree = ET.ElementTree(root)
tree.write(xml_file)
# Use the function
convert_complex_pdf("complex_document.pdf", "complex_output.xml")
XML Output Structure
The output XML will structure content based on pages, making it easy to query or transform. For further examples and detailed XML schema, refer to docs/pdf_to_xml.md.
