I want to edit the config file of a program that is an XML:
<software>
<settings>
...
<setting name="local directory" type="string">/home/username/</setting>
...
</settings>
</software>
What is the easiest way to do this from a bash script?
Thanks

Create a new XML or XSLT fileFrom the File menu, select New. The New File dialog box appears. Select XML File to create a new XML file; or, select XSLT File to create a new XSLT style sheet. Select Open.
To edit any config file, simply open the Terminal window by pressing the Ctrl+Alt+T key combinations. Navigate to the directory where the file is placed. Then type nano followed by the filename that you want to edit. Replace /path/to/filename with the actual file path of the configuration file that you want to edit.
Using xmlstarlet:
xmlstarlet val -e file.xml
xmlstarlet ed -u "//settings/setting/@name" -v 'local directory2' file.xml
xmlstarlet ed -u "//settings[1]/setting/@name" -v 'local directory2' file.xml
# edit file inplace
xmlstarlet ed -L -u "//settings/setting/@name" -v 'local directory2' file.xml
Depending on what you want to do, you may want to use some XML-specific tooling (to handle character encodings, to maintain XML well-formedness etc.). You can use the normal line-oriented tools, but unless you're careful (or doing something trivial) you can easily create non-compliant XML.
I use the XMLStarlet command line set. It's a set of command line utilities for specifically parsing/manipulating XML.
