Hi, I am trying to understand the set of advantages that XmlTextReader offers
in comparison to SAX and have some queries regarding the same, they are as.. 1> Reader carries a doc pointer in its structure…
_xmlTextReader xmlDocPtr doc;
/* when walking an existing doc */ In what all cases this document is created from the xml document being
parsed? Is it only created if I invoke “xmlTextReaderExpand” ? 2> Is the document (tree) generated for schema validation (XML Schema)
using reader? Can it be done on the stream also, like the one expected from API
xmlSchemaValidateStream ? 3> To what extent entities supported in reader? Can I use external
entities also along with reader? 4> How is error
reported incase of parsing failure using reader? Is is redirected using the
error handlers registered (Generic and structured error handlers)? Please let me know incase you need any clarification on the above
mentioned queries. Thanks in advance. !! Regards, Harbhanu |
