Answer 1

您可以将文本拆分为数组：

> str = 'sharemarket is a minnow by world standards, at just 2.5 per cent of the global sharemarket value. <br><br>One approach for local investors might be via an international share fund, with the fund manager'
=> "sharemarket is a minnow by world standards, at just 2.5 per cent of the global sharemarket value. <br><br>One approach for local investors might be via an international share fund, with the fund manager"
> rows = str.split('<br><br>')
=> ["sharemarket is a minnow by world standards, at just 2.5 per cent of the global sharemarket value. ", "One approach for local investors might be via an international share fund, with the fund manager"]

然后，将其写入pdf：

rows.each {|row| pdf.text row}
