## Processing Libraries



### Legend for Use Case Tags



| Tag               | Description                                                                                                                        |

| ----------------- | ---------------------------------------------------------------------------------------------------------------------------------- |

| **DOM**           | Libraries that support building or navigating XML trees via the Document Object Model.                                             |

| **SAX**           | Libraries that use event-driven parsing, emitting parsing events (start tag, end tag, etc.) instead of building an in-memory tree. |

| **Validation**    | Support for XML schema validation (DTD, XSD, Relax NG, etc.).                                                                      |

| **XPath**         | Libraries that support querying XML documents using XPath expressions.                                                             |

| **XSLT**          | Libraries with support for XML transformation using XSLT stylesheets.                                                              |

| **Serialization** | Libraries that convert between native data structures and XML (marshal/unmarshal).                                                 |



💡 Use these tags to quickly identify what capabilities each library provides. 💡
