asp.net - 如何在 xsl for-each 列表中对变量进行排序

Question

我有以下代码：

<asp:RadioButtonList ID="PriceSelect_{$ModuleId}" runat="server" RepeatDirection="Vertical"  NOWRAP="TRUE">
  <xsl:for-each select="Page/ArrayOfWebPrice/WebPrice">
    <xsl:variable name ="RateCode" select ="RateCode"></xsl:variable>
    <xsl:variable name ="RateStructure" select ="RateStructure"></xsl:variable>
    <xsl:variable name ="Price" select="concat($CurrencySymbol, format-number(Price, concat('#,###,##0.', substring($zeros, 1, $CurrencyPrecision))), ' ', $CurrencyCode)"></xsl:variable>
    <asp:ListItem  value="{$RateStructure}_{$RateCode}_Price" Enabled ="true" Selected ="true" text="{$Price}" >
    </asp:ListItem>
  </xsl:for-each>
  <asp:ListItem  value="Other" Enabled ="true" Selected ="false">
  </asp:ListItem>
</asp:RadioButtonList>

我正在尝试对每个列表项的顺序进行排序，它们是数字。
