In case you have an xml file (or string) like this:

<ImageData>
    <Path>Res\image.xaml</Path>
</ImageData>

...and a xaml dictionary in the file "Res\image.xaml" like this:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Image x:Key="imageKey" Source="img.jpg"/>
</ResourceDictionary>

...you can get the Source path of the Image element like this (using LINQ to XML):

private string GetImagePath(string xmlString)
{
    XElement xmlData = XElement.Parse(xmlString);

    XElement pathElement = xmlData.XPathSelectElement("ImageData/Path");

    if (pathElement == null) return null;

    string xamlPath = pathElement.Value;

    XElement xamlData = XElement.Load(xamlPath);

    XElement imageElement = xamlData.XPathSelectElement("//Image");

    if (imageElement == null) return null;

    XAttribute pathAttribute = imageElement.Attribute("Source");

    return pathAttribute == null ? null : pathAttribute.Value;
}

This is, of course, a rough guideline on how to do it, certainly you would tweak this after some experimenting, to suit your model.

You'll need to be a little bit more specific about how the image file information is formatted, but if it's just stored in the XAML as a file path, using .NET's XMLTextReader should do the trick. c-sharpcorner.com has some good code samples that should help you out.

XAML is XML, so parse as XML and use any of those approaches to extracting the required data.
