xml档转成文字档

请教各位大大....小弟使用WebClient.DownloadString Method 将一个xml档转成文字档
code如下：

WebClient client = new WebClient();
string reply = client.DownloadString("http://xxxxxx");

将得到的reply 写成123.txt档
原本的xml档如下：

程序代码：

<?xml version="1.0" encoding="big5" ?>

转成123.txt档后变这样：

 <?xml version="1.0" encoding="big5" ?><Book><execute_result>success</execute_result><data_item><Publishers>A-list</Publishers><name>AAA</name><MarketJMark>N</MarketJMark><cond_list><cond><name>con1</name><value>2</value></cond><cond><name>con2</name><value>1</value></cond><cond><name>con3</name><value>4</value></cond></cond_list><commodity_list><commodity_data><commodity>A-e</commodity><name>A-c</name><kind>F</kind><point_num>1</point_num><JMark>N</JMark><month_list><month>201112</month><month>201201</month><month>201202</month></month_list></commodity_data><commodity_data><commodity>AA-e</commodity><name>AA-c</name><kind>F</kind><point_num>3</point_num><JMark>N</JMark><month_list><month>201112</month><month>201203</month><month>201205</month><month>201207</month><month>201209</month><month>201212</month></month_list></commodity_data></commodity_list></data_item><data_item><Publishers>B-list</Publishers><name>BBB</name><MarketJMark>N</MarketJMark><cond_list><cond><name>con1</name><value>2</value></cond><cond><name>con2</name><value>1</value></cond><cond><name>con3</name><value>4</value></cond><cond><name>con4</name><value>8</value></cond></cond_list><commodity_list><commodity_data><commodity>B-e</commodity><name>B-c</name><kind>F</kind><point_num>4</point_num><JMark>N</JMark><month_list><month>201112</month><month>201203</month><month>201206</month<month>201209</month></month_list></commodity_data><commodity_data><commodity>BB-e</commodity><name>BB-c</name><kind>F</kind><point_num>2</point_num><JMark>N</JMark><month_list><month>201112</month><month>201201</month><month>201203</month><month>201205</month><month>201207</month><month>201208</month></month_list></commodity_data></commodity_list></data_item><data_item><Publishers>C-list</Publishers><name>CCC</name><MarketJMark>N</MarketJMark><cond_list><cond><name>con1</name><value>2</value></cond><cond><name>con2</name><value>1</value></cond><cond><name>con3</name><value>4</value></cond></cond_list><commodity_list><commodity_data><commodity>C-e</commodity><name>C-c</name><kind>F</kind><point_num>1</point_num><JMark>N</JMark><month_list><month>201112</month><month>201203</month><month>201206</month><month>201209</month></month_list> </commodity_data></commodity_list></data_item> </Book>

小弟想要在123.txt档中读出以下的结构：

A-list B-list C-list
------- ------- -------
A-e    B-e    C-e
201112 201112 201112
201201 201203 201203
201202 201206 201206
201209 201209

AA-e   BB-e
201112 201112
201203 201201
201205 201203
201207 201205
201209 201207
201212
201208

取得每个list中的每个商品及每个商品的每个月份
请教各位大大，该如何取得呢....
