# DeleteRange(MarkupAttribute)

Method in [MarkupParseResult](https://docs.yarnspinner.dev/2.1/api/csharp/yarn.markup/yarn.markup.markupparseresult)

## Summary

Deletes an attribute from this markup.

```csharp
public MarkupParseResult DeleteRange(MarkupAttribute attributeToDelete)
```

## Remarks

This method deletes the range of text covered by `attributeToDelete` , and updates the other attributes in this markup as follows:

* Attributes that start and end before the deleted attribute are unmodified.
* Attributes that start before the deleted attribute and end inside it are truncated to remove the part overlapping the deleted attribute.
* Attributes that have the same position and length as the deleted attribute are deleted, if they apply to any text.
* Attributes that start and end within the deleted attribute are deleted.
* Attributes that start within the deleted attribute, and end outside it, have their start truncated to remove the part overlapping the deleted attribute.
* Attributes that start after the deleted attribute have their start point adjusted to account for the deleted text.

This method does not modify the current object. A new [MarkupParseResult](https://docs.yarnspinner.dev/2.1/api/csharp/yarn.markup/yarn.markup.markupparseresult) is returned.

If `attributeToDelete` is not an attribute of this [MarkupParseResult](https://docs.yarnspinner.dev/2.1/api/csharp/yarn.markup/yarn.markup.markupparseresult), the behaviour is undefined.
