Hello.
How can I write code in if condition, if there is no tags in XML.
For example, my xml source is like this :
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<m2m:cin xmlns:m2m="http://www.onem2m.org/xml/protocols"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ty>4</ty>
</m2m:cin>
And I can write if condition like this, if there is a tag :
filter {
xml {
remove_namespaces => true
xpath => ["/cin/ty", "ty"]
}
if [ty] {
...
}
}
but, if there is no tag, is it right?
if(![ty]) {
...
}
