combine two sed commands

Question

how to combine the below sed commands in Linux

sed -rn 's/.*MsgFlow="([^"]*)".*/\1/p'  ADVQCC_OUTPUT_BRK1

and

sed -n 's:.*<ProcessDtm>\(.*\)</ProcessDtm>.*:\1:p' ADVQCC_OUTPUT_BRK1

Thanks

Answer 1

Usually, you can simply concatenate sed commands like several s commands with an embedded semicolon:

sed 's/some/another/;s/stuff/thing/'

In your case, one command uses extended regular expressions (ERE), the other basic regular expressions, so you need to convert one or the other:

sed -n 's/.*MsgFlow="\([^"]*\)".*/\1/p;s:.*<ProcessDtm>\(.*\)</ProcessDtm>.*:\1:p' ADVQCC_OUTPUT_BRK1

or with ERE:

sed -En 's/.*MsgFlow="([^"]*)".*/\1/p;s:.*<ProcessDtm>(.*)</ProcessDtm>.*:\1:p' ADVQCC_OUTPUT_BRK1

Remark: I changed -r to -E for selecting ERE, because this is understood by more versions of sed.

Answer 2

I think the more closer variant of two command combination will be (POSIXly):

sed -ne 's/.*MsgFlow=\"\([^"]*\)\".*/\1/p' -ne 's/.*<ProcessDtm>\\\(.*\\\)<\/ProcessDtm>.*/\1/p' ADVQCC_OUTPUT_BRK1

Or simpliest:

sed -e 's/.*MsgFlow=\"\([^"]*\)\".*/\1/' -e 's/.*<ProcessDtm>\\\(.*\\\)<\/ProcessDtm>.*/\1/' ADVQCC_OUTPUT_BRK1

But i need input example to get more exact result.
