Example 1-1 Initializing and Parsing Sequence for the Pre-Unified C API, One Document at a Time

The following pseudo-code demonstrates how to initialize and parse documents, one at a time, using the old C APIs. Contrast this with Example 1-2.

#include <oraxml.h>
uword err;
xmlctx *ctx = xmlinit(&err, options);
for (;;)
{
   err = xmlparse(ctx, URI, options);
   ...
   /* DOM operations */
   ...
   /* recycle memory from document */
xmlclean(ctx);
}
xmlterm(ctx);

Example 1-2 Initializing and Parsing Sequence for the Unified C API, One Document at a Time

The following pseudo-code demonstrates how to initialize and parse documents, one at a time, using the new C APIs. Contrast this with Example 1-1.

#include <xml.h>
xmlerr err;
xmldocnode *doc;
xmlctx *xctx = XmlCreate(&err, options, NULL);
for (;;)
{
   doc = XmlLoadDom(xctx, &err, "URI", URI, NULL);
   ...
   /* DOM operations */
   ...
XmlFreeDocument(xctx, doc);
}
XmlDestroy(xctx);

Example 1-3 Initializing and Parsing Sequence for the Pre-Unified C API, Multiple Documents and Simultaneous DOM Access

The following pseudo-code demonstrates how to initialize and parse multiple documents with simultaneous DOM access using the old C APIs. Contrast this with Example 1-4.

xmlctx *ctx1 = xmlinitenc(&err, options);
xmlctx *ctx2 = xmlinitenc(&err, options);
err = xmlparse(ctx1, URI_1, options);
err = xmlparse(ctx2, URI_2, options);
...
/* DOM operations for both documents */
...
xmlterm(ctx1);
xmlterm(ctx2);

Example 1-4 Initializing and Parsing Sequence for the Unified C API, Multiple Documents and Simultaneous DOM Access

The following pseudo-code example demonstrates how to initialize and parse multiple documents with simultaneous DOM access using the new C APIs. Contrast this with Example 1-3.

xmldocnode *doc1;
xmldocnode *doc2;
xmlctx *xctx = XmlCreate(&err, options, NULL);
doc1 = XmlLoadDom(xctx, &err, "URI", URI_1, NULL);
doc2 = XmlLoadDom(xctx, &err, "URI", URI_2, NULL);
...
/* DOM operations for both documents*/
...
XmlFreeDocument(xctx, doc1);
XmlFreeDocument(xctx, doc2);
...
XmlDestroy(xctx);
