## Parse xml: force as an array
In XML, if your array has a single item, then yq doesn't know its an array. This is how you can consistently force it to be an array. This handles the 3 scenarios of having nothing in the array, having a single item and having multiple.
Given a sample.xml file of:
```xml
<zoo><animal>cat</animal></zoo>
```
then
```bash
yq -oy '.zoo.animal |= ([] + .)' sample.xml
```
will output
```yaml
zoo:
animal:
- cat
```
## Parse xml: attributes
Attributes are converted to fields, with the default attribute prefix '+'. Use '--xml-attribute-prefix` to set your own.
