我有项目使用xslt文件使用以下代码显示记录:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:param name="OffersPerPage" select="4" />
  <xsl:template match="/" xml:space="default">
<div class="offers_section">
<script>
  $(document).ready(function() {
  $(".offers_page").hide();
  $("#OfferPage1").show();
  });
  function OffersPageChange(CurrentPage, NewPage)
  {
   $("#OfferPage" + CurrentPage).hide();
$("#OfferPage" + NewPage).show();
$("$offers_section").focus();
return false;
  }
</script>
<xsl:choose>

代码背后的代码是:

void Load_Category(int CategoryId)
    {
        string skinPath = PortalSettings.ActiveTab.SkinPath;

        XDocument XDocOffers = new XDocument(new XElement("Offers"));
        SqlDataProvider provider = new SqlDataProvider();

        SQLConnection.Open();

        SQLConnectionAnswers.Open();

        SqlCommand sqlComm = new SqlCommand("OffersGetOffersByCategory", SQLConnection);
        sqlComm.CommandType = CommandType.StoredProcedure;

        sqlComm.Parameters.Add(new SqlParameter("@CategoryId", SqlDbType.Int)).Value = CategoryId;

        SqlDataReader OffersReader = sqlComm.ExecuteReader();

        string OfferId;
        string Partner;
        string Description;

        {
            OfferId = OffersReader["OfferId"].ToString();

            Phone = OffersReader["Phone"].ToString();
            LegalInformation = OffersReader["LegalInformation"].ToString();

            Twitter = OffersReader["Twitter"].ToString();
            LegalOnOfferPage = OffersReader["LegalOnOfferPage"].ToString();
            onclick = "_gaq.push(['_trackEvent', 'Book Now', 'click', '" + Partner + "']);";
            Emailonclick = "_gaq.push(['_trackEvent', 'Email', 'click', '" + Email + "']);";
            XElement NextOffer =

                new XElement("OfferId", OfferId),
                new XElement("Partner", Partner),
                new XElement("Description", Description),
                new XElement("ImageSource", ImageSource),
                new XElement("Url", Url),

                new XElement("Emailonclick", Emailonclick)
              );

            XDocOffers.Element("Offers").Add(NextOffer);
        }

        OffersReader.Close();
        SQLConnection.Close();

        string XSLTFile = Server.MapPath(skinPath + "xslt/offers.xslt");
        if (File.Exists(XSLTFile))
        {
            StringWriter XSLTOutput = new StringWriter();
            XmlWriter XMLOutput = XmlWriter.Create(XSLTOutput);

            // Load the style sheet.
            XslCompiledTransform xslt = new XslCompiledTransform();
            xslt.Load(XSLTFile);

            XsltArgumentList ArgumentsQA = new XsltArgumentList();

            if (Settings.ContainsKey("OffersPerPage"))
            {
                ArgumentsQA.AddParam("OffersPerPage", "", Settings["OffersPerPage"].ToString());
            }
            else
            {
                ArgumentsQA.AddParam("OffersPerPage", "", "4");
            }

            ArgumentsQA.AddParam("BasePath", "", "/");

            // Execute the transform and output the results to a writer.
            xslt.Transform(XDocOffers.CreateReader(), ArgumentsQA, XMLOutput);

            //Output.Controls.Add(new LiteralControl(XSLTOutput.ToString().Replace("&amp;", "&")));
            Output.Controls.Add(new LiteralControl(HttpUtility.HtmlDecode(XSLTOutput.ToString())));
        }
        else
        {
            Output.Controls.Add(new LiteralControl("Cannot find XSLT file"));
        }
    }

问题是:

现在以替换行的某种不同格式显示详细信息。目前,每个优惠都有左侧的图像和右侧的描述,对于备用行现在我想在左侧显示描述,右侧显示图像,我以前从未使用过xslt文件,任何人都可以帮助...或者建议我怎么样实现这一目标。

等待你的答案..

答案 0 :(得分:1)

我已经解决了这个问题.. 这是解决方案,我们不需要更改c#代码中的任何内容(代码隐藏),我们刚刚更改了xslt文件来执行此操作,作为内置函数的xslt文件编号。

我使用了mod如下:

 <xsl:for-each select=". | following-sibling::Offer[(position()) &lt; $OffersPerPage]" >
<xsl:choose>
         <xsl:when test="position() mod 2 = 1">
             data 1
         </xsl:when>
         <xsl:otherwise>
             data 2
         </xsl:otherwise>
   </xsl:choose>
 </xsl:for-each>

这都是.....
