Xmltodict
xmltodict is a Python library that provides bidirectional serialization between XML documents and dictionaries. It functions as a parser that converts marked-up input into key-value pairs and a serialization utility that transforms dictionaries back into structured XML documents.
The project includes an incremental stream processor that uses depth-based callbacks to handle large XML files while maintaining constant memory usage. It features a namespace manager for mapping prefixes and declarations, as well as a security sanitizer that blocks external entity expansion and validates element names to prevent injection attacks.
The library provides capabilities for data type enforcement, such as forcing specific elements to be represented as lists regardless of child count. It also supports data post-processing through user-defined callbacks and offers configurable controls for expanding, collapsing, or skipping namespaces during the conversion process.
Features
- XML Serialization - Transforms Python dictionaries back into structured, well-formed XML documents with support for namespaces and formatting.
- XML to Dictionary Mappers - Parses XML trees into nested Python dictionaries by mapping tags to keys and text nodes to values.
- XML Parsing - Converts marked-up documents into dictionaries using configurable rules for prefixes and whitespace.
- Stream-Based Parsing - Implements an event-driven streaming parser to handle large XML files with constant memory usage.
- Stream Processors - Provides an incremental stream processor that handles large XML files with constant memory usage.
- Large Scale XML Processing - Processes massive XML files incrementally using streaming callbacks to maintain low memory usage.
- XML Serialization Formats - Generates structured XML files by transforming Python dictionaries into formatted markup.
- Object-to-XML Mapping - Transforms Python dictionaries into structured XML documents with formatting and list expansion options.
- XML to JSON Converters - Converts XML documents into nested Python dictionaries, enabling JSON-like manipulation of marked-up data.
- XML Namespace Management - Manages complex XML namespaces by mapping prefixes and controlling their appearance in converted data.
- XML Namespace Declarations - Maps XML namespaces to prefixes or collapses them into simplified keys based on configurable rules.
- Incremental Parsing - Processes large XML files incrementally using callbacks to maintain constant memory usage.
- Type Enforcement - Enforces specific data types, such as wrapping elements in lists, during the XML parsing process.
- List Type Enforcement - Forces specific XML elements to be treated as lists even if only a single child exists.
- XML External Entity Prevention - Blocks the resolution of external entities during parsing to prevent resource exhaustion and injection attacks.
- XML Processing Security - Implements security measures including external entity blocking and element name validation to prevent XML injection attacks.
- Data Value Transformations - Provides user-defined callbacks to transform XML values or attributes on the fly during conversion.
- Namespace Representation Controls - Provides controls to expand, collapse, or skip namespaces during the parsing process.
- Symmetric Input-Output Mappings - Uses shared transformation rules to enable consistent bidirectional conversion between dictionaries and XML.
- Data Loading Extraction - Makes XML feel like working with JSON.
- Documentation and Processing - Tool for converting XML to Python dictionaries.
- HTML and XML Processing - Handling XML data with JSON-like syntax.
