utility_data_model_dump_data_to_xml

Dump the data in a DataModel into a xmlNodePtr (as used in libxml).

Warning: this function uses a DataModelIter iterator, and if model does not offer a random access (check using get_access_flags), the iterator will be the same as normally used to access data in model previously to calling this method, and this iterator will be moved (point to another row).

Parameters:

model	a DataModel
parent	the parent XML node
cols	an array containing which columns of model will be exported, or null for all columns
rows	an array containing which rows of model will be exported, or null for all rows
use_col_ids	set to true to add column ID information
nb_cols	the number of columns in cols
nb_rows	the number of rows in rows

Returns:

true if no error occurred
