pdfExtractXFAData
Extract XFA form data.
char *pdfExtractXFAData(PDFHandle pdf, int *length)
This function extracts the raw XFA (XML Forms Architecture) form data
from the PDF file.
If there is no XFA form this function returns NULL.
The string is returned, and *length is filled in with the
string length. The caller is responsible for freeing the string with
the pdfFreeMemory function.
C:
char *buf;
int length;
if ((buf = pdfExtractXFAData(pdf, &length))) {
/* process the XFA data */
...
pdfFreeMemory(buf);
} else {
/* there is no XFA data in this PDF file */
}
