Extracting text from XML elements is easily done with
xml/sax addon, see example below. Also it can be done
with xml/xslt as shown in xml/xslt/test/test01.ijs
NB. =========================================================
NB. object oriented sax parser specialization
NB. extract text of specific elements
require 'xml/sax'
saxclass 'psax4'
TAG=: 'test'
startDocument=: 3 : 'PATH=: R=: $0'
endDocument=: 3 : 'R'
startElement=: 4 : 'PATH=: PATH,<y'
endElement=: 3 : 'PATH=: }:PATH'
characters=: 3 : 'if. TAG -: >@{: PATH do. R=: R,<y end.'
NB. =========================================================
cocurrent 'base'
TEST4=: 0 : 0
<body><test>s123</test><test>zz</test><q>z456</q><test>s456</test></body>
)
0 : 0 NB. Test
process_psax4_ TEST3
TAG_psax4_=: 'td'
process_psax4_ fread jpath '~addons/xml/sax/test/table.xml'
)
