Shell Programming and Scripting

:wall: Hi,

I have an XML file with 5 tags. I need to pass values to the XML file from a shell script that will replace values in 2 of the tags. I cannot hardcode the tag values in XML and use replace command in script as the values are likely to change.
Please help !!!!!!!!!!!

I have 2 variables a and b . a=12345 and b=8976.
In the XML there are 2 tags suppose:
<xyz>111</xyz>
<uio>222</uio>
Now , I want to pass value of 'a' i.e. '12345' to XML tag <xyz> and replace '111' by '12345'. Again value of 'b' i.e. '8976' will be passed to XML tag <uio> and '222' will be replaced by '8976'.
How to do this in 1 go ?
Hope i have made myself clear !!!!!
