用rails REXML解析xml文件？

Question

我該如何解析這個XML文件？

<resultset> 
−<row> 
<field name="Table Name">table_1</field> 
<field name="Quant of Rows">2</field> 
<field name="Total Size Mb">0.02</field> 
</row> 
−<row> 
<field name="Table Name">table_2</field> 
<field name="Quant of Rows">1</field> 
<field name="Total Size Mb">0.02</field> 
</row> 
</resultset> 

我正在使用REXML。

Answer 1

table_data = [] 
    xml = File.read('file1.xml') 
    doc, posts = REXML::Document.new(xml), [] 
    doc.elements.each('resultset/row') do |table_row| 
     table_data << {:table_name => table_row.elements[1].text, 
     :record_count => table_row.elements[2].text, 
     :size_in_mb => table_row.elements[3].text 
     } 
    end
