1. XML library by Thomas Parslow

I tried this code:
include print.e
include xml.e
object xml
xml = xml_Parse("<aaa>bbb</aaa>")
print(2, xml )
xml = xml_GetSubElement(xml, "aaa")
print(2, xml)
but the output is:
{{1,{"aaa",{},{{3,"bbb"}}}}}
C:\EUPHORIA\include\xml.e:321 in function xml_GetSubElement()
subscript value 2 is out of bounds, reading from a sequence of length 1
... called from xmlcoba.ex:9
--> see ex.err
Press Enter...
Am I right in using xml_GetSubElement?
Thanks!

The reason for this is that xml_Parse returns a sequence where each
element represents an xml document (A xml document always has a single
root element). So this would work:
--include print.e
include xml.e
object xml
xml = xml_Parse("<root><aaa>bbb</aaa></root>")
print(2, xml )
if length(xml) < 1 or xml[1][XML_pTYPE] != XML_tELEMENT then
puts(2,"Unable to parse XML fragment\n")
abort(1)
end if
xml = xml[1]
xml = xml_GetSubElement(xml, "aaa")
print(2, xml)
XML.E is not a very good library at all, it's slow, hard to work with
and non-conformant, this is mainly because I didn't really have any
idea of how to work with XML when I wrote it :)
I've written a completely different XML parser which I'm now using in
my Jabber client, it's available in the Marvin source package at
http://marvin-jabber.sourceforge.net/ (it's in the eebax directory).
If anyone is interested I'll write some docs and examples and release
it separately...

There is getxml() in strtok too, altho i set up the xml in the database about
1990, before there was a standard. It has various options, like get the 3rd
<tag>, etc, docs not included. YMMV, batteries not included.
