Using rex simple-xml with javascript extensions

Hello,

I am running into a problem where I am attempting to use rex command similar to the Custom Chart Overlay in Simple XML examples.

I know my search works in simple xml.


earliest=-2hr latest=now
| fields time_taken, cs_uri_stem, sc_status
| rex field=sc_status \"(?<200>2\d\d)\"
|rex field=sc_status \"(?<300>3\d\d)\"
| rex field=sc_status \"(?<400>4\d\d)\"
| rex field=sc_status \"(?<500>5\d\d)\"
| rex field=cs_uri_stem \"(?<uri>/[\w\d]{0,13})\"
| eval uri=lower(uri) |bucket _time span=2m
| stats count(200) as 200, count(300) as 300, count(400) as 400, count(500) as 500, avg(time_taken) as AvgTime by _time uri

but in the following it doesnt


<div id="base-search"
class="splunk-manager"
data-require="splunkjs/mvc/searchmanager"
data-options='{
"earliest_time": "-2@h",
"latest_time": "now",
"cache": "60",
"search": ".... earliest=-2hr latest=now
| fields time_taken, cs_uri_stem, sc_status
| rex field=sc_status \"(?&lt ;200&gt ;2\d\d)\"
| rex field=sc_status \"(?&lt ;300&gt ;3\d\d)\"
| rex field=sc_status \"(?&lt ;400&gt ;4\d\d)\"
| rex field=sc_status \"(?&lt ;500&gt ;5\d\d)\"
| rex field=cs_uri_stem \"(?&lt ;uri&gt ;/[\w\d]{0,13})\"
| eval uri=lower(uri) |bucket _time span=2m
| stats count(200) as 200, count(300) as 300, count(400) as 400, count(500) as 500, avg(time_taken) as AvgTime by _time uri"
}'>

What gives?

Thanks in advance

mathu has it, you have to use a backslash to escape the double quotes.

I also had to escape the existing backslashes in my regex:

| rex field=cst_ls_segment \"LS\\d+\\s+(?&lt;segment&gt;.*)\"

Cheers,

Luke.

I would post the job inspector, but as soon I add regex it never makes it to the search manager.

can you post the resulting search (from the job inspector)?

Sorry I forgot to added the double backslash. The part that having problems is the rex extraction. It does nots like the html encoding of the greater/ less than symbols or the symbol.

Use a backslash to escape the double quotes.
Single quotes don't work because of "data-options" which is already quoted with singles.

Make sure you either escape the double quotes within the search string or use single quotes around it instead.
