thanks Jorn. The only alternative is to use xpath UDF? Works as shown below but tedious
Like the example below *$cat employees.xml* <employee> <id>1</id> <name>Satish Kumar</name> <designation>Technical Lead</designation> </employee> <employee> <id>2</id> <name>Ramya</name> <designation>Testing</designation> </employee> *Step:1 Bring each record to one line, by executing below command* $cat employees.xml | tr -d '&' | tr '\n' ' ' | tr '\r' ' ' | sed 's|</employee>|</employee>\n|g' | grep -v '^\s*$' > employees_records.xml *$cat employees_records.xml* <employee> <id>1</id> <name>Satish Kumar</name> <designation>Technical Lead</designation> </employee> <employee> <id>2</id> <name>Ramya</name> <designation>Testing</designation> </employee> *tep:2 Load the file to HDFS* *$hadoop fs -mkdir /user/hive/sample-xml-inputs* *$hadoop fs -put employees_records.xml /user/hive/sample-xml-inputs* *$hadoop fs -cat /user/hive/sample-xml-inputs/employees_records.xml* <employee> <id>1</id> <name>Satish Kumar</name><designation>Technical Lead</designation> </employee> <employee> <id>2</id> <name>Ramya</name> <designation>Testing</designation> </employee> *Step:3 Create a Hive table and point to xml file* *hive>create external table xml_table_org( xmldata string) LOCATION '/user/hive/sample-xml-inputs/';* *hive> select * from xml_table_org;* *OK* <employee> <id>1</id> <name>Satish Kumar</name> <designation>Technical Lead</designation> </employee> <employee> <id>2</id> <name>Ramya</name> <designation>Testing</designation> </employee> *Step 4: From the stage table we can query the elements and load it to other table.* *hive> CREATE TABLE xml_table AS SELECT xpath_int(xmldata,'employee/id'),xpath_string(xmldata,'employee/name'),xpath_string(xmldata,'employee/designation') FROM xml_table_org;* Dr Mich Talebzadeh LinkedIn * https://www.linkedin.com/profile/view?id=AAEAAAAWh2gBxianrbJd6zP6AcPCCdOABUrV8Pw <https://www.linkedin.com/profile/view?id=AAEAAAAWh2gBxianrbJd6zP6AcPCCdOABUrV8Pw>* http://talebzadehmich.wordpress.com *Disclaimer:* Use it at your own risk.
