Extracting attributes from XML Schema

amanno — Fri, 30 Jun 2017 22:08:32 GMT

I know there has to be a nice way to do this upon indexing in Splunk...I have a large XML file that I am indexing on the tag info however when each event is index I want some information from higher up the "tree" of the XML to be placed into that event. For a small example in:

 <Baseball>
         <player name="freese" number="23">
             <stats>
                       <info index=0>
                           <Team>Pittsburgh Pirates</Team>
                           <BA>.249</BA>
                       </info>
                       <info index=1>
                          <Team>Cardinals</Team>
                          <BA>.248</BA>
            </stats>
        </player>
         <player name="Pujols" number="5">
             <stats>
                       <info index=0>
                           <Team>LA Angles</Team>
                           <BA>.236</BA>
                       </info>
                       <info index=1>
                          <Team>Cardinals</Team>
                          <BA>.307</BA>
            </stats>
        </player>
    </Baseball>

I would like to have events that have all the information in the info tag as well as the two attributes of player name and number. Any ideas would be greatly appreciated.

First off, your sample XML seem to have info end tags missing. You can use spath or xpath command to extract fields from XML. Based on the your needs you can extract individual field or as multi valued fields.

| makeresults 
| eval xml_data="<Baseball>
  <player name=\"freese\" number=\"23\">
      <stats>
        <info index=0>
            <Team>Pittsburgh Pirates</Team>
            <BA>.249</BA>
        </info>
        <info index=1>
           <Team>Cardinals</Team>
           <BA>.248</BA>
        </info>
     </stats>
  </player>
  <player name=\"Pujols\" number=\"5\">
    <stats>
        <info index=0>
            <Team>LA Angles</Team>
            <BA>.236</BA>
        </info>
        <info index=1>
           <Team>Cardinals</Team>
           <BA>.307</BA>
        </info>
    </stats>
  </player>
 </Baseball>"
 | spath input=xml_data path=Baseball.player{1}{@name} output=name
 | spath input=xml_data path=Baseball.player{1}{@number} output=number
 | spath input=xml_data path=Baseball.player{@name} output=names
 | spath input=xml_data path=Baseball.player{@number} output=numbers
 | spath input=xml_data path=Baseball.player.stats.info.Team output=Team
 | spath input=xml_data path=Baseball.player.stats.info.BA output=BA
 | table xml_data name names number numbers Team BA
