parsing with Mojo::DOM - perl

Question

I am using Mojo::UserAgent->new to fetch some XML which has the following format:
<row>
<td> content1 </td>
<td> content2 </td>
<td> content3 </td>
</row>
<row>
<td> content4 </td>
<td> content5 </td>
<td> content6 </td>
</row>
Is it possible to view the results like this:
content1,content2,content3
content4,content5,content6
below are the query i am using which get different resutls
$ua->get($url)->res->dom->at->(row)->children->each(sub {print "$_\t"})

Answer 1

Sure, that's absolutely possible and not hard with Mojo::Collection working behind the scenes.
Code
# replace this line by your existing $ua->get($url)->res->dom code
my $dom = Mojo::DOM->new(do { local $/ = undef; <DATA> });
# pretty-print rows
$dom->find('row')->each(sub {
my $row = shift;
say $row->children->pluck('text')->join(', ');
});
Data
__DATA__
<row>
<td> content1 </td>
<td> content2 </td>
<td> content3 </td>
</row>
<row>
<td> content4 </td>
<td> content5 </td>
<td> content6 </td>
</row>
Output
content1, content2, content3
content4, content5, content6
Some comments
each evaluates a code ref for each element of a collection (which is what find returns).
pluck returns a Mojo::Collection object with the return values of the given method name (text in this case). This is just a fancy way to map simple stuff.
text automagically trims the element content.
join joins all elements of the Mojo::Collection object together, all td elements of a row in this case.
Your code doesn't even compile, but using at won't work anyway because it returns just the first matching DOM element, not all. You want to iterate all rows.
HTH!
