XML Extraction

Builder

I have a datasource that reads in events in XML format. Could someone please help me build a props.conf that will extract all fields and show the events in treeview. Sample event below

Mon Apr 28 16:45:57 EDT 2014 name="TOPIC_msg_received" event_id="ID:404040" msg_dest="SplunkTopic" msg_body="<?xml version="1.0" encoding="utf-8"?><ELLogInputLayout xmlns="http://www.test.com/1"><ELLogInputMessage>    <Header>      <LogEventTypeCode>ERROR</LogEventTypeCode>      <LogSeverityCode>CRITICAL</LogSeverityCode>      <LogEventDateTime>9999-12-31T23:59:59.9999999-05:00</LogEventDateTime>    </Header>    <SourceInformation>      <EAPMId>2</EAPMId>      <HostMachineName>HostMachineName3</HostMachineName>      <HostEnvironmentName>HostEnvironmentName3</HostEnvironmentName>      <ComponentId>ComponentId3</ComponentId>      <ComponentName>ComponentName3</ComponentName>      <ApplicationEventCorrelationId>ApplicationEventCorrelationId3</ApplicationEventCorrelationId>      <UserId>UserId3</UserId>      <UserSrc>UserSrc3</UserSrc>      <BusinessDomainId>BusinessDomainId3</BusinessDomainId>      <BusinessDomainName>BusinessDomainName3</BusinessDomainName>    </SourceInformation>    <ErrorInformation>      <ErrorCode>ErrorCode3</ErrorCode>      <ErrorDescription>ErrorDescription3</ErrorDescription><DetailedErrorInformation>DetailedErrorInformation3</DetailedErrorInformation>    </ErrorInformation>    <DetailedLogInformation>anyType</DetailedLogInformation>   </ELLogInputMessage></ELLogInputLayout>"

Hello

Have your tried KV_MODE = XML in props.conf ??

From docs:

KV_MODE = [none|auto|multi|json|xml]
* Used for search-time field extractions only.
* Specifies the field/value extraction mode for the data.
* Set KV_MODE to one of the following:
        * none: if you want no field/value extraction to take place.
        * auto: extracts field/value pairs separated by equal signs.
        * multi: invokes the multikv search command to expand a tabular event into multiple events.
    * xml : automatically extracts fields from XML data.
    * json: automatically extracts fields from JSON data.
* Setting to 'none' can ensure that one or more user-created regexes are not overridden by
  automatic field/value extraction for a particular host, source, or source type, and also
  increases search performance.
* Defaults to auto.
* The 'xml' and 'json' modes will not extract any fields when used on data that isn't of the correct format (JSON or XML).

This may not work as the event is not pure xml (its a combination of key value pair with embedded xml). You might have to extract all xml fields using field extractor.

Yes, I tried using KV_MODE = XML but it is not picking up. Is the only way to do individual field extraction?

Try this.

props.conf

[yourSourceType]
NO_BINARY_CHECK = 1
TIME_FORMAT = %a %b %d %H:%M:%S %T %Y
pulldown_type = 1
REPORT-xmlkv = xmlkv-alternative

transforms.conf

[xmlkv-alternative]
REGEX = <([^\s\>]*)[^\>]*\>([^<]*)\<\/\1\>
FORMAT = $1::$2

That extracted all the fields, thanks! Wish there was a way to get a pull down view but this will do the trick if that's not possible.

Could you be more specific what you mean by pull down view?

when you have an input that is true json or xml you can have the view of the events in a tree structure where you hit the + sign to see nested information.

Hi,

I have a .log file which has mix of system logs and in between request & response XMLs of actual transactions going within my application. I only want those XML transactions only to be shown in splunk and do not want to see the other logging information. Is there a way to achieve this?

I like this solution using transforms.conf

[views_std]
MV_ADD = 1
REGEX = \<(\w+[^\n\/\>]+)\/?\>([^\<\n][^\<]*)\<
FORMAT = $1::$2
CLEAN_KEYS = true

[views_param]
MV_ADD = 1
REGEX = \<(\w+ [^\n\/\>]+)\/?\>
FORMAT = param::$1
CLEAN_KEYS = true

[views_option]
MV_ADD = 1
SOURCE_KEY = param
REGEX = (\w+(?: \w+)*)="(?!host|source|sourcetype|index|splunk_server)(\w+)"
FORMAT = $1::$2
CLEAN_KEYS = true
