Xpath command is not giving result

jayadevanepSPL — Mon, 12 Sep 2016 09:00:11 GMT

I have a XML embedded in another XML with escape characters

<Audit>
<tracker>XXXXX123</tracker>
<Message>&lt?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?>&ltABCxmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:qu=&quot;http://qqqq.xsd&quot; xmlns:v1=&quot;http://www&quot; xmlns:xsd=&quot;http://www.w3.org/2001/XMLSchema&quot;>
&ltRM>
&ltCode>111&lt/Code>
&ltState>Avilable&lt/State>
&lt/RM> 
&ltRM>
&ltCode>222&lt/Code>
&ltState>Not avilable&lt/State>
&lt/RM>
&ltRM>
&ltCode>333&lt/Code>
&ltState>Not sure&lt/State>
&lt/RM>
&lt/ABC>
</Message>
</Audit>

I am suing below command to extract and convert the embedded XML to correct format. This page is not allow to how escape characters so removed the ";"

| rex "\<Message\>(?<Message>.*)\<\/Message\>" 
| eval Message1 = replace (Message,"&lt","<")
| eval Message2 = replace (Message1,"&gt",">")
| eval Message3 = replace (Message2,"&quot","\"")

Message3 giving below output

<?xml version="1.0" encoding="UTF-8"?><ABC xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:qu="http://qqqq.xsd" xmlns:v1="http://www" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<RM>
<Code>111</Code>
<State>Avilable</State>
</RM>
<RM>
<Code>222</Code>
<State>Not avilable</State>
</RM>
<RM>
<Code>333</Code>
<State>Not sure</State>
</RM>
</ABC>

Now I want to get RM in to one veriable if state is = “Not available”. I am using below command for that.

| xpath field=Message3  "// ABC / RM [State=' Not available ']" outfield=NAV

But NAV is not giving any result. Can you please help to fix the issue ?

Is this because of the presence of name space ?

Have you tried spath? http://docs.splunk.com/Documentation/Splunk/6.4.3/SearchReference/Spath

The value based filter is not supported in Splunk's spath. (see the spath documentation for supported functionalities). Something like this would work for your requirement (run anywhere example, first few lines are just to generate sample data).
