SVG Points Attribute Parser
Parse finite SVG points-attribute number pairs with comma/whitespace or sign separators; reject incomplete pairs and malformed separators.
Description
Parse finite SVG points-attribute number pairs with comma/whitespace or sign separators; reject incomplete pairs and malformed separators.
An SVG points attribute is a finite number sequence grouped into x/y pairs. Complete pairing is required even when separators vary.
When to use this tool
Parse finite SVG points-attribute number pairs with comma/whitespace or sign separators; reject incomplete pairs and malformed separators.
- Prepare the supplied value fields for this operation.
- Compare the complete example with the representation used by your own input before carrying the result into another step.
How to use the tool and how it works
- Enter value. Use the exact text syntax, units and index conventions explained below.
- Run the tool. If input validation fails, correct the supplied fields before interpreting any result.
- Read result.points. Interpret false, null and empty lists using the distinctions below; they can be valid outputs.
Parse the supported SVG number grammar and whitespace/comma separators. Reject an odd count and return consecutive coordinate pairs; empty text returns no points.1
| Input field | Meaning and representation | Accepted input |
|---|---|---|
| value | value. | Text; at most 8,192 UTF-16 code units, subject to the grammar above |
| Output field | Interpretation |
|---|---|
| result | Object containing the named outputs below. |
| result.points | The points list in the ordering and representation described above. |

}Limitations and assumptions
- This is not a path-data parser. No closure, units, transforms or geometric validity are inferred.
- Point pairs use [x,y], rectangles and viewBox use [x,y,width,height], and all coordinate units must be consistent. This tool does not read, render or modify an SVG document.
- Every declared top-level field is required and unexpected fields are rejected. Numeric inputs must be finite; ordinary text fields are bounded to 8,192 UTF-16 code units, with tighter operation-specific limits where stated.
- String lists have at most 128 entries of at most 128 code units; matrices have at most 128 rows and columns. Larger numeric lists and parsed JSON have separate bounded budgets. Nonfinite results and excessively large serialized outputs are rejected.
- Indexes are zero-based and spans have an exclusive end unless explicitly stated otherwise. A valid false, null or empty-list result is distinct from malformed input.
Alternative or Complementary methods
Use a full SVG parser or rendering engine when the task includes commands and CSS values outside the documented branch. Compare coordinates and transforms under the same units and viewport convention.
