C#/ASP.NET - Parse XML File

I have attached an example XML file as well as the VS solution file for the started project. Basically, I need to have the XML file that the user uploads parsed and certain element's values read. Based on the values, a text file should be created and saved with the translated/converted text output. More detail: Below is an outline of what I'd like to get started with. I've accomplished this already, though I only program as a hobby so I'm sure there are better and more efficient ways to accomplish this. Feel free to use whatever best practice methods you find necessary to complete the task below. The code to convert the XML values as well as the final text file itself should be protected to the best of your abilities from client view, as this project will eventually be available for pay-per-use and hosted online. For dev purposes you may output the text file to the webpage right now, though when the project is finished that will not happen. Contact me with any questions/clarifications. Should check to ensure that file uploader contains a ".xml" file. No other file types authorized. Should save XML file to 'UploadedXMLs' folder. Should parse XML file, reading defined element values below and bulding final text file. Should save final text file into 'ASA_Configs' folder. Final text file definition: - There is an element called 'system-name' in the XML File. - Assuming the value of 'system-name' is WGFW: - The final text file should have a string 'hostname WGFW'. - There is an element called 'interface-list' in the XML File. - Within the 'interface-list' element, there is a descendant called 'physical-if'. - If 'physical-if' does NOT exist, then the whole 'interface' should be skipped for processing. - If 'physical-if' does exist, then: - Translate the following to final text file. - 'if-num' value of x: - If 'ASA 5520' is selected in drop-down --> interface GigabitEthernet 0/x - Else --> interface Ethernet 0/x - 'enabled' value of 1 --> no shut - 'name' value of x --> nameif x - 'ip' value of x.x.x.x, 'netmask' value of y.y.y.y --> ip address x.x.x.x y.y.y.y - 'auto-negotiation' value of 0: - 'link-speed' value of x, 'full-duplex' value of 1 - --> speed x duplex full - 'link-speed' value of x, 'full-duplex' value of 0 - --> speed x duplex half - 'auto-negotiation' value of 1 --> no output necessary I'd like to see how well this is done, as this project is very large and I don't want to continue with additional conversions without first seeing these steps completed. Please let me know if you have additional questions and I will respond promptly.
