Parse xml file
I am trying to create a shell script that will parse an xml file (file attached).

Code:
 awk '/Id v=/ { print }' Test.xml  | sed 's!<Id v=\"\(.*\)\"/>!\1!' > output.txt

An output.txt file is created but it is empty. It should contain the value 222159 in it. Thanks.
Test.xml (2.1 KB)

The file doesn't contain the string "Id v="
If you are looking for "Id" / "id" values, below is the code

Code:
awk -F "[<>]" '/<Id>|<id>/ {print $3}' Test.xml

Thank you very much. Is it possible to search for multiple criteria at once?

For example, Id, Source,Accession,TestName,etc. Thanks.


Code:
 awk -F "[<>]" '/<Id>|<id><Source>|<source<Accession>|<accession><TestName>|<testname>/ {print $3}' Test.xml

Yes, it is possible
And your code is almost correct
Code:
 awk -F "[<>]" '/<Id>|<id>|<Source>|<source>|<Accession>|<accession>|<TestName>|<testname>/ {print $3}' Test.xml

Thank you again.

One last question: can the ID,Source,Accession,TestName be used as the row header with the coressponding value next to it?

For example,
Code:
Id              222159
Source       GTR
Accession   GTR000222159
TestName   STAT3 mutation analysis

Thank you.

If I wanted the:

Code:
A               B
Id              222159
Source       GTR
Accession   GTR000222159
TestName   STAT3 mutation analysis

separated by a tab, would an ' FS='|' OFS='\t' be put after the $3)? I am learning awk so I really appreciate your help. Thanks.
