## XPathNavigator::SelectSingleNode(SharedPtr\<XPathExpression\>) method


Selects a single node in the [XPathNavigator](../) using the specified [XPathExpression](../../xpathexpression/) object.

```cpp
virtual SharedPtr<XPathNavigator> System::Xml::XPath::XPathNavigator::SelectSingleNode(SharedPtr<XPathExpression> expression)
```


| Parameter | Type | Description |
| --- | --- | --- |
| expression | SharedPtr\<XPathExpression\> | An [XPathExpression](../../xpathexpression/) object containing the compiled [XPath](../../) query. |

### ReturnValue

An [XPathNavigator](../) object that contains the first matching node for the [XPath](../../) query specified; otherwise **nullptr** if there are no query results.

```


| Parameter | Type | Description |
| --- | --- | --- |
| xpath | String | A [String](../../../system/string/) representing an [XPath](../../) expression. |
| resolver | SharedPtr\<IXmlNamespaceResolver\> | The [IXmlNamespaceResolver](../../../system.xml/ixmlnamespaceresolver/) object used to resolve namespace prefixes in the [XPath](../../) query. |

### ReturnValue

An [XPathNavigator](../) object that contains the first matching node for the [XPath](../../) query specified; otherwise **nullptr** if there are no query results.
