Parse XML File using HIVE

Posted on by Sumit Kumar

In this post , we will learn how to parse XML file using hive.

I am using below xml file for this example.

jmdbks@hadoop:~$ cat test.xml
<test><name>Sumit Kumar</name><properties><age>29</age><sex>male</sex></properties></test>
<test><name>Amit Kumar</name><properties><age>30</age><sex>male</sex></properties></test>
<test><name>Aditya Kumar</name><properties><age>23</age><sex>male</sex></properties></test>
<test><name>Priya Kumar</name><properties><age>24</age><sex>Female</sex></properties></test>
<test><name>Rohan Kumar</name><properties><age>20</age><sex>male</sex></properties></test>
<test><name>Nitish Kumar</name><properties><age>29</age><sex>male</sex></properties></test>
jmdbks@hadoop:~$

Below are the Step by Step Procedure to parse XML file using hive .

Step 1:- Create table with single column.

create table test_xml(col string);

Step 2:-Loading XML file into single column table.
load data local inpath '/home/jmdbks/test.xml' into table test_xml;

Step 3:-Create table(Final_table) with required file that is available in XML file.

create table test_xml2(name string,age string,gender string);

Step 4:- insert data into Final_table using hive xpath_string().

hive> insert overwrite table test_xml2 select xpath_string(col,'test/name'),xpath_string(col,'test/properties/age'),xpath_string(col,'test/properties/sex') from test_xml;
hive> select * from test_xml2 ;
OK
