utilityDataModelDumpDataToXml

bool utilityDataModelDumpDataToXml(gda.data_model.DataModel model,  libxml2.types.NodePtr parent,  int[]  cols,  int[]  rows,  bool  useColIds)

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

Warning: this function uses a #GdaDataModelIter iterator, and if model does not offer a random access (check using [gda.data_model.DataModel.getAccessFlags]), 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 #GdaDataModel
`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
`useColIds`	set to true to add column ID information

Returns

true if no error occurred
