Somebody of you LiveCode gurus, can you help me to read this file without the use of RevXML?
Code: Select all

<forversion8>
<lastversion>810</lastversion>
<downloadurl>http://www.mymacapp.com/downloads/</downloadurl>

Hi,
Did you have a look at my book? It contains examples that use the revXML features as well as examples using vanilla LiveCode scripts.
You can use offset to get the location of a tag, e.g.
Code: Select all
put "<forversion8" into myTag
put offset(myTag,myXML) + len(myTag) + 1 into myStart
put slash after char 1 of myTag
put offset(myTag,myXML,myStart) - 1 into myEnd
add myStart to myEnd
This gives you the starting point and end point of the XML tree you're interested in. (I didn't test this particular example; you may have to fiddle with the +1 and -1). You can do the same with other tags. If you write a function for it, you'll be able to retrieve any tag using the same function. Sometimes, you may have to use the function multiple times:
Code: Select all
put vanillaXml("forversion8",myXML) into myTree1
put vanillaXML("downloadUrl",myTree1) into myUrl
Kind regards,
Mark

Hi Mark,
I swear that it is the only section that I have not read in your book!
I'm going now to study it. Thanks!
