Using XPath for reading attribute and content of XML

I used this type of XPath functionality for creating a rotating image based on an XML file.

<-- First the XML  -->
<images>
<image href="img1">1</image>
<image href="img2">2</image>
</images>

<-- Next the XPath for C#  -->
<-- get all image hrefs (and other attributes) -->
images//image

<-- get image value at image position 1 -->
images//image[position()=1]

<-- get href attribute at images/image position 1 -->
images//image[position()=1][@href]
