Example: Using the XPathXmlStreamReader Component

Use XPathXmlStreamReader with FilePollSource, which reads XML data and parses it using XPath rules. Then pass the records to AsapSink, which publishes them to the Server.

  1. Start Event Stream Processor.
    Operating System Step
    UNIX Open a terminal window:
    1. Start the example cluster:

      start_server_cluster.sh

    2. Start the project on the cluster:

      start_project.sh
    Windows Open a command window:
    1. Start the example cluster:

      start_server_cluster.bat

    2. Add project to the cluster, and start it on the cluster:

      start_project.bat
  2. Start esp_subscriber to subscribe to the project that is running on the cluster.
    Operating System Step
    UNIX Open a terminal window and enter:

    ./esp-subscribe.sh
    Windows Open a command window and enter:

    esp-subscribe.bat
  3. Start the FilePollSource (with XPathXmlStreamReader) and AsapSink components.
    Operating System Step
    UNIX Open a terminal window and enter:

    ./XPathXmlStreamReader.sh
    Windows Open a command window and enter:

    XPathXmlStreamReader.bat
    Data from the insert.xml file publishes to the Server.
