Replace string after equal sign

Question

I have a XML file with the following structure:

<ns1:ReservationPCC pseudoCityCode="1234" pseudoCityType="Booking" supplierService="Sabre"/>

and I would like to replace the pseudoCityCode by let's say abcd.

I'm trying the following:

sed -e's/pseudoCityCode=.*/pseudoCityCode="abcd" /g'

But, it returns:

<ns1:ReservationPCC pseudoCityCode="abcd"

Adding a white space:

sed -e's/pseudoCityCode=.*\s/pseudoCityCode="abcd" /g'

will return the following:

<ns1:ReservationPCC pseudoCityCode="abcd" supplierService=Sabre/>

Why did the pseudoCityType disappear? What am I missing?

Answer 1

sed 's/pseudoCityCode="[^"]*"/pseudoCityCode="abcd"/'<<<'<ns1:ReservationPCC pseudoCityCode="1234" pseudoCityType="Booking" supplierService="Sabre"/>'

or like @Ed Morton said:

sed 's/\(pseudoCityCode="\)[^"]*/\1abcd/'<<<'<ns1:ReservationPCC pseudoCityCode="1234" pseudoCityType="Booking" supplierService="Sabre"/>'
