Hello,
Despite many trials, i am failing extracting the value of an attribute
with xmlXPath().
Here is an example:
text = ["<main>"
" <itag target=""valueA"" url=""valueB"" />"
" <itag target=""valueA2"" url=""valueB2"" />"
" <itag target=""valueA3"" url=""valueB3"" />"
"</main>"
];
doc = xmlReadStr(text)
Now, we want to select all <itagentries for which the targetattribute
has a given value (say valueA2), and for them, get the related urlvalue:
-->e = xmlXPath(doc, "//itag[@target=""valueA2""]") // works:
e =
XML List
size: 1
you got a list with one element
but ehas no attributes fields. So i cannot get its url contents:
-->e.name
ans =
itag
e(1).name
fyi e.name is a shortcut to get all the nodes name in the list.
-->e.attributes
!--error 999
%XMLSet_e: Unknown field: attributes
e(1).attributes
How is it possible to do what we expect, whether it is?
Reading examples on the official xmlXPath webpage did not help...
Thanks for any hints
Samuel
Best regards
Calixte
