In encode mode, the xml filter converts input stream (which must contain valid UTF-8 characters) into a form suitable for inclusion into a XML or HTML document, i.e. it replaces <, >, and & with <, >, and &, correspondingly, and replaces invalid characters with their numeric character reference representation.
In decode mode, a reverse operation is performed.
The filter does not take arguments.
The following object, declared in mailutils/filter.h describes the filter:
extern mu_filter_record_t mu_xml_filter;
The example below shows how to create an instance of this filter in encode mode for reading:
int rc; /* Return code */ mu_stream_t flt; /* Filter stream */ mu_stream_t input; /* Input stream */ initialize_input_stream (&stream); rc = mu_filter_stream_create (&flt, input, "xml", MU_FILTER_DECODE, MU_STREAM_READ);
