Parameters

v [in]

Type: BSTR

The selector string.

pel [out, retval]

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Standards information

Remarks

The document search order is depth-first. This method returns the first element found. To find all matching nodes, use IElementSelector::querySelectorAll.

The scope of the returned element node is limited to the descendants of the starting element node. If the starting element is document, the search returns nodes from the entire document.

This method does not return the starting element node. For example, div.querySelector("p div") will never return the DIV element that it starts with.

The pseudo-class selectors :hover, :focus, and :active are supported. Selectors that contain :visited or :link are ignored and no elements are returned.

You can search namespaced elements using a selector syntax based on prefix instead of the namespaceURI, for example "nsPrefix \: element", where "nsPrefix" is the prefix of a given element.

Selectors are described in detail in Understanding CSS Selectors and W3C Selectors.
