It has been tested with your input sample:
Code:
grep -E "<(timestamp|severity|message)" file | paste -sd"\t\t\n" | grep -E "ERROR.*thumbnail" | tr '\t' '\n'
 <timestamp>2019-03-13T04:52:49.648-05:00</timestamp>
 <severity>ERROR</severity>
<message>cannot make thumbnail image</message>

What are your OS and grep versions?

That IS the complete code, running with your input sample. Did you replace "file" with your input file name?

hi RudiC, thanks for your support, issue resolved, need small info what -sd will do in your code..?

man paste:
Quote:
-d, --delimiters=LIST
reuse characters from LIST instead of TABs

-s, --serial
paste one file at a time instead of in parallel

HOW did you resolve the issue?

gnu version
Code:
grep -B1 -A7 "ERROR" file | grep "<timestamp\|<severity\|<message"
