p:xquery — The standard p:xquery step.
The p:xquery step applies an
XQuery query to the sequence of documents
provided on the source port.
| Input port | Primary | Sequence | Content types |
|---|
| source | ✔ | ✔ | any |
| query | | | text xml |
| Output port | Primary | Sequence | Content types |
|---|
| result | ✔ | ✔ | any |
| Option name | Type | Default value |
|---|
| parameters | map(xs:QName,item()*)? | () |
| version | xs:string? | () |

Errors
| Code | Description |
|---|
err:XC0009 | It is a
dynamic error (err:XC0009) if the specified XQuery version
is not available. |
err:XC0101 | It is a dynamic error (err:XC0101) if a document
appearing on port source cannot be represented in the XDM version associated with
the chosen XQuery version, e.g. when a JSON document contains a map and XDM 3.0 is used. |
err:XC0102 | It is a dynamic error (err:XC0102) if any key in option
parameters is associated to a value that cannot be represented in
the XDM version associated with the chosen XQuery version, e.g. with a map, an array,
or a function when XDM 3.0 is used. |
err:XC0103 | It is a dynamic error (err:XC0103) if any error occurs during
XQuery’s static analysis phase. |
err:XC0104 | It is a dynamic error (err:XC0104)
if any error occurs during XQuery’s dynamic evaluation phase. |
