How to retrieve value using jq - jq

Question

Below is the JSON we have, and I want to filter only these below values (that is available under "text" field). I want to use the jq command for this. I have tried this command, but it is resulting in an error:
jq -r'.[].content.data[]["content-item"]'|jq -r '.[]| select (.text |startswith("^23.acmestable.0."))'
Expected result:
23.acmestable.0.22
23.acmestable.0.23
23.acmestable.0.24
23.acmestable.0.25
Which is this JQ query runs for "hardcoded" value:
'.[].content.data[]["content-item"]'|jq -r '.[]| select (.text=="23.acme.0.23")'
and returns:
{
"text": "23.acmestable.0.23"
}
Sample JSON:

Just traverse and select in a single jq call. The ? filters out the null values.
jq -r '.[].content.data[]."content-item"[].text | select(startswith("23.acmestable.0."))?'
23.acmestable.0.0-SNAPSHOT
23.acmestable.0.24
23.acmestable.0.25
23.acmestable.0.22
23.acmestable.0.23

Note: startswith takes a plain (sub)string, not a regular expression. Replace it with test to perform a regex matching instead. Demo
