Best of luck. A two step approach can certainly work.

Cheers!

Cheers Jason,
I appreciate the reply. I guess I wanted this to be a bit more dynamic. Maybe I can just write something that does the geocoding separately and then the page looks at the geocoded cities.

Luis,

If you are having a large number of entries in the xml file I recommend storing actual lat/ lng coordinates rather than geocoding the whole list everytime the webpage is pulled up. Performance is slow when geocoding a large number of entries. You can look at my most post “Google Map API – Markers with Pop Up Windows” which uses lat/ lng coordinates rather than an address as an example. Good luck with your project!

Hello Jason,
This example is great! Got me up and running after trying several things. Admittedly, I am a total beginner with Google Maps API. I had a similar issue to Dan whilst trying to call out say, 100 or 200 addresses. Is this the 100ms limit I heard about? How to curb this? Check out the map here:

And the xml file:
http://dhubfablab.cat/ccloud/maps/cities3.xml.

Any help would be appreciated! Really, excellent example!

I’m trying to add a form field that when submitted adds the address marker (as nicely demonstrated here) that updates an XML file and the XML file spits out the content that is in the sidebar, adding the point and making the marker clickable/pop-out. I’ve found help on each of these things separately but am having a time putting it together.

I’ve tried a function that deletes the last line “” and then reads it after the fopen, write, but nothing was written. Everytime I get one thing working something else breaks. Having a tough time as I’m new to Google Maps.

Any help would be amazing.

Hi Jason,

I got the database to output the records in XML file, but its in a different format then the one you posted above. By looking at the following data from the database generated XML file, how could I adapt my aspx code so that it selects the address value from the XML file generated by the database?

This is the xml file that i get:

adsad@ad.com
asda
asd
asd
xxxx
Male
Withdean
0

asd@ad.com
asd
ad
asd
xxxx
Female
Hailsham

As you can see there is no quotation mark or ‘Marker’/'Markers’ element specified. What do I do?

Hi Jason,
Thanks for the link, but I found the code that you gave at the top of this page much easier. Is there no way the XML file could hold the addresses based on the search criteria when a query is initialised. Is there no way the database updates the xml file?

Also the source you mentioned, does not actually say how I can get specific data to be shown based on the preferences of the user who is logged in? Any tips?

Thanks Jason, I will have a look at it.

Xavier – Check out this link for code samples on how to Combine External Data Sources with a MS SQL Server Database to Create Google Maps Using AJAX and ASP.NET. Seems to fit the bill of what you are trying to do.
