# Path
|
|
|
|
The path operator can be used to get the traversal paths of matching nodes in an expression. The path is returned as an array, which if traversed in order will lead to the matching node.
|
|
|
|
You can get the key/index of matching nodes by using the `path` operator to return the path array then piping that through `.[-1]` to get the last element of that array, the key.
|
|
|
|
## Map path
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a:
|
|
b: cat
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a.b | path' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
- a
|
|
- b
|
|
```
|
|
|
|
## Get map key
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a:
|
|
b: cat
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a.b | path | .[-1]' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
b
|
|
```
|
|
|
|
## Array path
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a:
|
|
- cat
|
|
- dog
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a.[] | select(. == "dog") | path' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
- a
|
|
- 1
|
|
```
|
|
|
|
## Get array index
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a:
|
|
- cat
|
|
- dog
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a.[] | select(. == "dog") | path | .[-1]' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
1
|
|
```
|
|
|
|
## Print path and value
|
|
Given a sample.yml file of:
|
|
```yaml
|
|
a:
|
|
- cat
|
|
- dog
|
|
- frog
|
|
```
|
|
then
|
|
```bash
|
|
yq '.a[] | select(. == "*og") | [{"path":path, "value":.}]' sample.yml
|
|
```
|
|
will output
|
|
```yaml
|
|
- path:
|
|
- a
|
|
- 1
|
|
value: dog
|
|
- path:
|
|
- a

|
- 2
