# xml:space Handling in XAML
|
|
|
|
The `xml:space` attribute is an XML-defined attribute that declares the significant white-space processing behavior within an object element. This behavior is relevant for all content (inner text) contained within the element where `xml:space` is declared, and also scopes to child elements.
|
|
|
|
## XAML Attribute Usage
|
|
|
|
```xaml
|
|
<object xml:space="preserve" />
|
|
```
|
|
|
|
\- or -
|
|
|
|
```xaml
|
|
<object xml:space="default" />
|
|
```
|
|
|
|
## Remarks
|
|
|
|
The definition for the `xml:space` attribute in XAML including its two possible values is derived from `xml:space` as defined as a "special attribute" by W3C specifications for XML.
|
|
|
|
The default value of the `xml:space` attribute is the literal value `"default"`. For the value `"default"`, or if `xml:space` is not indicated at all, the behavior of significant white-space parsing is the default handling, as defined in the topic [White-space processing in XAML](white-space-processing.md).
|
|
|
|
To preserve white space within object element content, specify `xml:space="preserve"` on that object element.
|
|
|
|
Under most interpretations, the `xml:space` attribute effects and the value of the attribute are scoped to child elements.
|
|
|
|
