Extract by XPath

  1. In Configuration, keep the global configuration default settings.
  2. Expand Root Paths, and click Add item to add a path.
  3. In Root path, enter the file or folder path to index.

    For example, /data/<USER>/xml-sample-data/contacts

  4. Expand XPaths, and click Add item.
    1. In Item n, enter the Xpath expressions to use. For example, /person/@name to retrieve the content of the name attribute, and text() to retrieve the content of a node, like a phone number.
    2. Enter the meta names associated with the content in Meta. For example, title and text.
  5. Click Apply to apply changes to the configuration.

    The connector configuration is complete. You can now scan and index the documents.

Example

Let us consider the following document: 

<root>
<D>
<M N="uri">050b-180b-536cc63c-000000040387-00</M>
<M N="session_dest_city">mountain view</M>
<M N="session_dest_country">us</M>
<M N="title">Nursing Portfolio</M>
</D>
<D>
<M N="uri">0203-6dd1-5369d61f-0000004e0b83-00</M>
<M N="session_dest_city">mountain view</M>
<M N="session_dest_country">us</M>
<M N="summary">##Subject: Proven in clinical trials</M>
</D>
</root>

If we configure in:

  • XPATH split processors, an item set to /root

  • XPath processors, the following Xpath items:

    Xpaths item

    configuration

    uri

    meta: uri

    XPath: /D/M[@N='uri']

    first attribute

    meta: session_dest_city

    XPath: /D/M[@N='session_dest_city']

    second attribute

    meta: session_dest_country

    XPath: /D/M[@N='session_dest_country']

    third attribute

    meta: summary

    XPath: /D/M[@N='summary']

The following metas are added to the document: 

uri:0203-6dd1-5369d61f-0000004e0b83-00
session_dest_country:us
session_dest_city:mountain view
summary:##Subject: Proven in clinical trials
