XMLSample Data

We will use the sample XML data given in the following for configuring SQL queries and database URL string. You can download the following data as a XML file, place it in a folder and follow the steps to test the DB connector.

Configure SQL Query

  • To fetch data from the XML, a select SQL query must be provided.
  • It is mandatory to map a unique field to uid
  • The query should follow SQL SELECT query format with mappings. SQL Query for Database Collection
    SELECT <index field> as uid , <column name2> as title, <column name3> as content FROM <tablename> LIMIT 100
    Sample Query for XML sample data:
    SELECT [people].[personal.name.first] AS uid, [people].[personal.name.last] AS title,[people].[personal.age] AS age,[people].[personal.gender] AS gender,[people].[vehicles.type],[people].[vehicles.model],[people].[vehicles.insurance.company],[people].[vehicles.maintenance.date] FROM [people]
  • In the preceding query you can see the fields are representated interms of hierarchy example:
    [people].[personal.name.first]
    [people].[vehicles.maintenance.date]

Reference for select queries for Database XML Connector

If you have more than 100 entries in a table, specify the number of documents to be indexed by giving LIMIT value in the query. For example:
SELECT <index field> as uid , <column name2> as title, <column name3> as content FROM <tablename> LIMIT 100
Otherwise, a minimum of 50 rows will be indexed.

Database Collection Settings

  • Select database type as XML from the dropdown menu.
  • Enter the database URL string in the format as shown here:
    jdbc:xml:DataModel=Relational;URI=C:\xmljson\person.xml;
  • Provide the exact URI of your xml file.
  • In XMLPath provide the main object in the format $.people'
  • Save the settings.
  • Check the settings by clicking Test Database Collection. The database connection has to be successful for the indexing to work.

Index and Search

  • Start indexing from the Index tab or dashboard.

Search results in regular search and faceted search are shown as follows:
