How to replace a same value fpr different variables with different values?

Hi,

Could anyone help me on the below problem

,

I am having a .xml file as a input file with >1000 lines
In that i want to replace some values,
ex:

Code:

<name>username</name>
  <value>admin</value>
  <name>password</name>
  <value>admin</value>

.
.
.

now i want to replace the 'username' value as 'admin123' instead of 'admin' but the 'password' value must be 'admin'.

here i used sed command to replace the value, but it replacing the both values.

Please can anyone help me out from this...

What error would that be?

Code:

$ sed "/[uU][sS][eE]...[mM][eE]/{N;s/admin/admin123/g;}" file
<name>/JDBC/userName</name>
<value>admin123</value>
<name>/JDBC/password</name>
<value>admin</value
<name>/JNDI/username</name>
<value>admin123</value>
<name>/JNDI/password</name>
<value>admin</value>

Scott,

Code:

 sed: -e expression #1, char 7: unknown command: `u'

The above error has been displayed when i executed the below command

Code:

 sed "/JDBC/userName/{N;s/admin/admin123/g;}" input.xml

the last command whic you gave is working for username
but for password?
What i mean that if '/' are present in between the words which we are searching then the above command is not working.

Please advise on this?

If you want to include a / in the pattern either escape it (\/), or use a different separator:

Code:

sed "@/JDBC/userName@.....@" ....

Changing the password is not fundamentally different from changing the username.

And, please:

And now i want to change it to only one value
that means
If i want to change it to JDBC/password value then it doesnt effect to the JNDI/password value.

---------- Post updated at 06:15 AM ---------- Previous update was at 06:09 AM ----------

I tried with that
but it thrown error

Code:

$ sed "@JNDI/password@{N;s/admin/4dm1n/g;}" input.xml
sed: -e expression #1, char 1: unknown command: `@'
