Replace dynamic content in XML file

Question

Quick Summary: I need to create a Bash script to change the text within a node automatically every week. The script will match the node and replace the text inside them (if this is possible)? How would I do this? Long Summary: I host a Minecraft server which has shops, each of which have their own .xml file in the /ShowcaseStandalone/ffs-storage/ directory. Every Sunday my server restarts and executes several commands into the terminal to reset several things. One thing that I am trying to make change is one of the shops. I am wanting to change the text in the node and the text in the node . I am simply wanting to take text from a .txt file in a different folder, and insert it into that node. The problem is, that the text in the node will change every week. Is there any way to replace a specific line or text within two nodes using bash? XML file: ```

Accepted Answer

You can use `xmlstarlet` to edit a `XML` file in a `shell` like this :

```
xmlstarlet edit -L -u "/scs-shop/price[@type='double']" -v '99.66' file.xml
```

NOTE

- `"/scs-shop/price[@type='double']"` is a Xpath expression

- see `xmlstarlet ed --help`
