Creating a custom text export file (inc. header & footer) from
I'm a little confused (and out of my depth), but are you saying that the data
will come out via a VBA parser different to what is actually held in the query/table?. I'm not a seasoned coder and find the arcane synatx of xml character encoding somewhat baffling. Regarding your suggestion that I should replace "&" with "& for the KML/XML file, though I can understand that it will allow for the '&' character to be viewed as '&' within google earth, it would look odd in the MS Access form/table. eg: Cable & Wireless Building Cable & Wireless Building So for now, I have to settle for 'Cable and Wireless Building' which is not an ideal state, but I don't know how to resolve it. "Brendan Reynolds" wrote: That's a separate issue, the & and characters have to be escaped because they have special meaning to the parser. See the section "2.4 Character Data and Markup" at the following URL ... http://www.w3.org/TR/REC-xml/ In short, you need to replace "&" with "&" and "" with "" The issue of encoding is described in the same article at section "4.3.3 Character Encoding in Entities" I know, it's not an easy read, and I can't explain it all. I'm not an expert on these issues, it's just something I had to muddle through as best I could for a specific project that I worked on about two years ago. If you think the code you have now will do what you need, that's great, but make sure to test it with characters outside the standard ASCII range if there is any possibility that such characters may ever be included in your real-world data. -- Brendan Reynolds "efandango" wrote in message ... Funny you should mention this Brendan, because I have been having problems with certains characters in the KML file such as these two: ' &. I had to change the ampersand (&) character to 'and' before google earth would accept them. I am not familiar with encoding formats, but assumed the KML was in UTF-8 encoding format. Here's a link to googles guide on KML where you can see that they use this type of encoding in their header file. http://code.google.com/apis/kml/docu...n/kml_tut.html Below is my resultant KML file with adjusted characterss which works fine in Google Earth, though it would be much better if it would take the & type characters: My KML example: ?xml version="1.0" encoding="UTF-8"? kml xmlns="http://earth.google.com/kml/2.0" Document nameRun Points 5/name Folder nameLocations/name open1/open PlacemarkdescriptionAscot Hotel/descriptionaddress11 Craven Road, W2, London, UK /addressname11 Craven Road, W2, London, UK/name/Placemark /Folder /Document /kml "Brendan Reynolds" wrote: I'm glad you're making progress. I think you'll find, though, that the resulting file is not, in fact, in UTF-8 encoding. You may find that this causes XML parsers to reject the file when it contains characters outside the standard ASCII range. I'm not aware of any way to specify the encoding to be used when using VBA IO commands. But you can probably avoid problems by changing the declaration to match the actual encoding being used, rather than trying to change the encoding to match the declaration. On my system, when using the VBA IO commands, the resulting file is in ISO-8859-1 encoding, so my declaration looks like this ... Print #intFile, "?xml version='1.0' encoding ='ISO-8859-1'?" I don't know whether VBA always uses this encoding, or whether it may vary between OS versions or language versions. If I remember correctly, I believe I used a utility or sample code that I found on the 'net to determine the actual encoding that VBA was using. I'm afraid, though, that it was some time ago, and I can't remember the details. If you really need to specify an encoding other than the one that VBA uses by default, I believe you can probably do that using Microsoft's XML parser, MSXML.DLL. I haven't actually done this, so I can't provide details, but if you want to look into it try searching on 'msxml' at MSDN (http://msdn.microsoft.com) -- Brendan Reynolds "efandango" wrote in message ... Brendan, That worked. It seems that while making changes to the code after Douglas's helpful input, I missed out some of John's essential code snippets. Following your suggestion, I went back to John's code, and incorporated them into Douglas's latter code suggestions, and it all worked in the end. So a HUGE thank you to John, Douglas and your good self for your help and guidance on this problem. For the record, here is the succesful code that will allow the user to choose a Run Number for a set of addresses and run it out to a Google Earth KML file. Cheers Fellas.
