I have a XML file that would like to use as a base layer in ArcGIS 10. What are the steps that I need to follow in order to open that file in ArcGIS 10?
The XML file does not have coordinates. When it's open it shows the following:
That XML isn't anything but "metadata". You need to track down "images/WA_Dayton_20110406_TM_geo_img_0.jpg"
The only useful data in the screenshot you added of the XML contents is the path to a .jpg file. Why don't you just locate that and bring it into ArcGIS? ArcGIS won't be able to understand the XML file directly.
You'll have to georeference it manually if it doesn't have an accompanying "world" file (.jgw, typically).
Side note: XML is just a markup language, and XML files are just text files. They can contain practically anything. It's up to the consumer of the file to be able to make sense of its contents, and ArcGIS has no idea what this flavor of XML is or what to do with its contents.
Edit: The saveasxml plugin that apparently was used to create the xml is just a plain 'ol xml writer.
So to expand on the original document and where you might go to accomplish what you need.
There are ways to create geopdf without terrago.
Old answer - doesn't seem to apply anymore with no comment I will remove
If the xml is a workspace document created by esri you would need to import it into a geodatabase of some variety (file, personal, sde).
Note: you have the option of just the schema or schema and data.
What does the XML file contain? X/Y points?
If the file only contains points you could simply convert the XML file to Excel format and then import the Excel file as such:
Tools -> Add XY data -> open the excel file -> define the x and the y fields -> output the final point features
If the file is more complicated than X/Y points could you post a sample so that we can see the elements and better inform you?
