Reading an XML file in MapBasic

[Hayden Fisher]

Hi,

 

I’ve created a type of XML file that I’d like to extract map settings from when start-up my mbx program. Has anyone found a way to (just) read this type of data format?

All observations and recommendation are greatly appreciated!

 

Regards Hayden

Hi Hayden,

MI Pro/MapBasic 8.5 included a library for handling XML files from MapBasic. I've used it, it woks.

Lars - Are there XML examples availble online? Haven't found any on
the PBMI website or PDF's.

Hi Hayden,

Have a look in the "HTTPlib" folder in Samples/MapBasic. There is an example on how to consume a RSS feed, which includes XML handling.

But the XML library is working much like how MSXML works, it's really more-or-less a standard library that's been opened up for MapBasic usage.

Hi Lars,

 

Thanks, I’m using MapBasic 8 right now, what are the implications if I swap to 8.5 will MapInfo Pro 8 users still be able to use the mbx’s?

No. Mbxs that use version 8.5 technology can not be used with MapInfo 8. Please remember an mbx simply calls functionality in mapinfo. The mbx itself don't know what to do with XML or anything else for that matter - it is all just instructions to MapInfo.

Not entirely true, as the XML (and HTTP and FTP) support in 8.5 is based on external DLL libraries.

However, these DLLs are part of the 8.5+ installation, and will not work in pre-8.5 versions.

There is an earlier version of the same XMLlib dll in pre-8.5 installations, but it's not really functional from a MapBasic point of view. I _have_ tried ;-)

So if you're stuck on version 8.0 and cannot upgrade, your only option is to build your own MB callable wrapper for MSXML, or use another XML library entirely (like open sourced Xerces?).
