Description
Match an identifier followed by one space and a nonempty parenthesized qualifier, with no parentheses inside either part.
Catalog identifiers and labels follow local formatting conventions. Splitting or recognizing a token's shape preserves structure without establishing that its identifier or classification is valid.
Match an identifier followed by one space and a nonempty parenthesized qualifier, with no parentheses inside either part.
When to use this tool
Use ISBN Binding Qualifier Parenthesis Token when you need one explicit catalog-label parsing or formatting step.
How to use the tool and how it works
- Enter token. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read identifier, qualifier. Use the output convention below.
Match an identifier followed by one space and a nonempty parenthesized qualifier, with no parentheses inside either part. Return both strings unchanged.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| token | Token | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| identifier | Identifier | Required. Text; maximum UTF-16 length 8192. |
| qualifier | Qualifier | Required. Text; maximum UTF-16 length 8192. |
{
"input": {
"token": "9781234567897 (paperback)"
},
"output": {
"identifier": "9781234567897",
"qualifier": "paperback"
}
}Limitations and assumptions
- The identifier is not checked as an ISBN; this recognizes a narrow binding-qualifier notation only.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
