我正在尝试使用 NSXMLParser 来解析以下数据：
<FORM ACTION="/prod/bwckgens.p_proc_term_date" METHOD="POST" onSubmit="return checkSubmit()">
<INPUT TYPE="hidden" NAME="p_calling_proc" VALUE="bwckschd.p_disp_dyn_sched">
<TABLE CLASS="dataentrytable" summary="This layout table is used for term selection."width="100%"><CAPTION class="captiontext">Search by Term: </CAPTION>
<TR>
<TD CLASS="dedefault"><LABEL for=term_input_id><SPAN class="fieldlabeltextinvisible">Term</SPAN></LABEL>
<SELECT NAME="p_term" SIZE="1" ID="term_input_id">
<OPTION VALUE="">None
<OPTION VALUE="201320">Spring 2013
<OPTION VALUE="201315">STAR/BGR: New Admits Fall 2012 (View only)
<OPTION VALUE="201310">Fall 2012 (View only)
<OPTION VALUE="201230">Summer 2012 (View only)
<OPTION VALUE="201220">Spring 2012 (View only)
<OPTION VALUE="201210">Fall 2011 (View only)
<OPTION VALUE="201130">Summer 2011 (View only)
<OPTION VALUE="201120">Spring 2011 (View only)
<OPTION VALUE="201110">Fall 2010 (View only)
<OPTION VALUE="201030">Summer 2010 (View only)
<OPTION VALUE="201020">Spring 2010 (View only)
<OPTION VALUE="201010">Fall 2009 (View only)
<OPTION VALUE="200930">Summer 2009 (View only)
<OPTION VALUE="200920">Spring 2009 (View only)
<OPTION VALUE="200910">Fall 2008 (View only)
<OPTION VALUE="200830">Summer 2008 (View only)
<OPTION VALUE="200820">Spring 2008 (View only)
</SELECT>
</TD>
</TR>
</TABLE>
<BR>
<BR>
<INPUT TYPE="submit" VALUE="Submit">
<INPUT TYPE="reset" VALUE="Reset">
</FORM>
我希望它将所有 VALUE 属性存储在字典或具有相应字符串的东西中，如下所示：
(201320, "Spring 2013")
(201315, "STAR/BGR: New Admits Fall 2012 (View only)")
(201310, "Fall 2012 (View only)")
....
我阅读了有关如何使用 XML Parser 的文档。我知道如何获取 VALUE 属性的值，但我不明白如何获取字符串的值，因为它们出现在元素 OPTION 关闭之后。
任何人都可以通过制作 XML 树来帮助我，向我展示一切是如何构造的，以及我将如何在每个 OPTION 属性之后提取字符串。
