:first, :last :n-child selectors

[deed02392]

Subject of the issue

When attempting to use the pseudo-selectors to get the n'th child items of nodes, I get the error:

[SyntaxError: unmatched pseudo-class :last]

Your environment

• version of node: run node --version v4.6.1
• version of npm: run npm --version v2.15.9

Steps to reproduce

x(markup, {
    raw_table: 'table.schedule@html',
    sched_type: ['tr@class'],
    date: ['td.date'],
    descr: ['tr td:last'] // This line
})(

Expected behaviour

descrshould be a collection of the innerText of all the last columns of all the rows parsed from 'markup'

Actual behaviour

Syntax error. Exit.

Shouldn't the selector be :last-child?

[Jacse]

As @kyleoliveiro mentions the correct selectors are :first-child, :last-child, :nth-child

Try this:

x(markup, {
    raw_table: 'table.schedule@html',
    sched_type: ['tr@class'],
    date: ['td.date'],
    descr: ['tr td:nth-last-child(1)'] // This line
})
