Frees memory for XML documents in memory (DOM representation).

document_id—The document to free and release memory for.

status—A value of 1 is returned if the operation was successful.

This routine is used to reclaim memory for documents parsed using XmlParse, or created from scratch using XmlNewDoc. Typically this is called after a document has been queried with XmlEvaluate and is not needed anymore, or if the document has been exported using XmlDocDump and the DOM representation in memory is no longer needed. Be careful to only call this routine once for a given document ID or a segmentation fault could result.

This example removes a DOM model from memory.

; Parse and evaluate a document

doc_id = XmlParse('chart.xml', /file)

table = XmlEvaluate(doc_id, '//*')

; Free the document

status = XmlFreeDoc(doc_id)
