> Hi All,
> We are planning to add the XMLLoader UDF in the piggybank repository.
> Here is the proposal with the user docs :-
> The load function to load the XML file
> This will implements the LoadFunc interface which is used to parse records
> from a dataset.
> This takes a xmlTag as the arg which it will use to split the inputdataset
> into
> multiple records.
> For example if the input xml (input.xml) is like this
> <configuration>
> <property>
> <name> foobar </name>
> <value> barfoo </value>
> </property>
> <ignoreProperty>
> <name> foo </name>
> </ignoreProperty>
> <property>
> <name> justname </name>
> </property>
> </configuration>
> And your pig script is like this
> --load the jar files
> register loader.jar;
> -- load the dataset using XMLLoader
> -- A is the bag containing the tuple which contains one atom i.e doc see
> output
> A = load '/user/aloks/pig/input.xml using loader.XMLLoader('property') as
> (doc:chararray);
> --dump the result
> dump A;
> Then you will get the output
> (<property>
> <name> foobar </name>
> <value> barfoo </value>
> </property>)
> (<property>
> <name> justname </name>
> </property>)
> Where each () indicate one record
