Module save 

XML save-context API (upstream xmlsave.c, 2.15.3).

xmlSaveToFd / xmlSaveToFilename / xmlSaveToBuffer / xmlSaveToIO create a save context; xmlSaveDoc / xmlSaveTree serialize into it; xmlSaveFlush / xmlSaveClose / xmlSaveFinish finalize it.

UPSTREAM-PARITY

xmlSaveCtxt is opaque in the public headers (xmlsave.h); the candidate defines its own internal representation — there is no ABI constraint on its layout. Behavior mirrors xmlsave.c: options XML_SAVE_FORMAT, XML_SAVE_NO_DECL, XML_SAVE_NO_EMPTY and the deprecated escape callbacks. Formatting/decl handling is provided by the tree serializer (serialize_node_opts), which mirrors upstream’s xmlSaveDoc/ xmlSaveTree/DumpState mechanics.

Courts

SAVE-* differential cases compare xmlSave* output byte-for-byte with the oracle DSO across option combinations.

Structs

_xmlSaveCtxt

Candidate-internal save context (opaque upstream).

Constants

XML_SAVE_FORMAT

XML_SAVE_FORMAT — format output (newlines + indentation).

XML_SAVE_NO_DECL

XML_SAVE_NO_DECL — don’t emit an XML declaration.

XML_SAVE_NO_EMPTY

XML_SAVE_NO_EMPTY — don’t emit empty tags.

Functions

xmlSaveClose^⚠

int xmlSaveClose(xmlSaveCtxt *ctxt) — flush, close and free the context.

xmlSaveDoc^⚠

Serialize doc into the save context’s output buffer.

xmlSaveFileTo^⚠

int xmlSaveFileTo(xmlOutputBufferPtr buf, xmlDocPtr cur, const char *encoding) — upstream xmlsave.c delegates to xmlSaveFormatFileTo(buf, cur, encoding, 0).

xmlSaveFinish^⚠

xmlParserErrors xmlSaveFinish(xmlSaveCtxt *ctxt) — flush, close, free; returns an xmlParserErrors code (XML_ERR_OK on success).

xmlSaveFlush^⚠

int xmlSaveFlush(xmlSaveCtxt *ctxt) — flush the output buffer.

xmlSaveFormatFileTo^⚠

int xmlSaveFormatFileTo(xmlOutputBufferPtr buf, xmlDocPtr cur, const char *encoding, int format) — serialize cur into an existing output buffer and close it (upstream xmlsave.c).

xmlSaveSetAttrEscape^⚠

int xmlSaveSetAttrEscape(xmlSaveCtxt *ctxt, xmlCharEncodingOutputFunc escape).

xmlSaveSetEscape^⚠

int xmlSaveSetEscape(xmlSaveCtxt *ctxt, xmlCharEncodingOutputFunc escape).

xmlSaveSetIndentString^⚠

int xmlSaveSetIndentString(xmlSaveCtxt *ctxt, const char *indent).

xmlSaveToBuffer^⚠

xmlSaveCtxt *xmlSaveToBuffer(xmlBuffer *buffer, const char *encoding, int options).

xmlSaveToFd^⚠

xmlSaveCtxt *xmlSaveToFd(int fd, const char *encoding, int options).

xmlSaveToFilename^⚠

xmlSaveCtxt *xmlSaveToFilename(const char *filename, const char *encoding, int options).

xmlSaveToIO^⚠

xmlSaveCtxt *xmlSaveToIO(xmlOutputWriteCallback iowrite, xmlOutputCloseCallback ioclose, void *ioctx, const char *encoding, int options).

xmlSaveTree^⚠

Serialize a node tree into the save context’s output buffer.
