Query selector / 3a

I'm doing js of% com_com% complexes that were not structured by me. To facilitate use Firebux or htmls to copy the selector ready. They return me this selector:

#dadosCadastraisa dadosCadastraisPessoaTablea 0a j1_data > tr > td:nth-child(1)

But the browser does not understand this Chrome Developer

I want to capture the tag: a

The html structure is this:

<form target="_self" enctype="application/x-www-form-urlencoded" action="http://pcnisapr02.prevnet/cnis/faces/pages/requerimento/painelcidadao/painelCidadao.xhtml" method="post" name="dadosCadastrais" id="dadosCadastrais">

    <span id="dadosCadastrais:dadosCadastraisContainer"><div class="ui-datatable ui-widget center-block dtp-painel-datatable" id="dadosCadastrais:dadosCadastraisPessoaTable">
            <div class="ui-datatable-header ui-widget-header ui-corner-top">
                <div class="btn-toolbar">
                    <div class="btn-group">
                        <span class="ico-user"></span> Dados Cadastrais
                    </div>

                </div>
            </div>
            <div class="ui-datatable-tablewrapper"><table role="grid">
