Module document 

Post-processing document wrapper with XML/DOM, ID management, and caching.

Port of LaTeXML::Post::Document. Wraps an XML::LibXML::Document (via the libxml crate) and provides:

• Namespace management
• ID tracking (idcache, reusable, reserved)
• XPath queries with registered namespaces
• Node manipulation (addNodes, removeNodes, cloneNode, etc.)
• Persistent cache (key-value store)

Structs

PostDocument

Post-processing document: wraps an XML document with ID management, namespace tracking, XPath helpers, and a persistent cache.

PostDocumentOptions

Options for creating a PostDocument.

Enums

Conjunction

Conjunction for joining node lists.

NodeData

Recursive representation for building XML nodes.

XMBranch

Which branch of an ltx:XMDual to follow — Perl’s $branch string argument to realizeXMNode, which is only ever 'content' or 'presentation'.

Constants

LTX_NSURI

The LaTeXML namespace URI.

Functions

element_children

Get element children of a node (skipping text, comments, etc.).

element_children_iter

Iterator version of element_children — walks the sibling chain lazily. Prefer this in hot paths that only need to read or filter children without materializing a Vec. Callers that need len() or random access still want the Vec version.

escape_xml

Escape a string for XML text content or a double-quoted attribute value.

get_xml_id

Get the xml:id attribute value from a node. Handles both namespace-aware and plain attribute access.
