我正在尝试使用csharp和xslt更新嵌套记录。我希望能够获得每个TopicAnalysisbyTopicAnalysisID的TopicAnswerID这里是我的xslt代码：
<xsl:when test="/root/BaseInfo/QueryData/m = 'EditAnalysis'">
<form action="topics.aspx?m=SaveExistingAnalysis" name="UpdateAnalysis"
enctype="multipart/form-data" method="post">
<input type="hidden" id="hiTopicID" name="hiTopicID"
value="{/root/BaseInfo/QueryData/TopicID}" />
<input type="hidden" id="hiTopicAnalysisID" name="hiTopicAnalysisID"
value="{/root/TopicAnalysisbyTopicAnalysisID/TopicAnalysisID}" />
<xsl:value-of select="/root/TopicAnalysisbyTopicAnalysisID/TopicName" />
</strong>
<xsl:value-of select="/root/TopicAnalysisbyTopicAnalysisID/TopicDescription" />
<xsl:value-of
select="/root/TopicAnalysisbyTopicAnalysisID/TopicAnalysisTextPending" />
<xsl:for-each select="/root/TopicAnalysisbyTopicAnalysisID">
<xsl:variable name="TOPIC_ANSWER_ID" select="TopicAnswerID" />
<xsl:value-of select="TopicQuestionText" />
<input type="hidden" id="hiTopicAnswerID" name="hiTopicAnswerID"
value="{TopicAnswerID}" />
<xsl:value-of select="AnswerTextPending" />
</xsl:for-each>
</form>
</xsl:when>
这是XML数据：

这是c代码：
else if (Request.Form["SaveExistingAnalysis"] != null)
{
cbancWS.TopicAnalysis tan = new cbancWS.TopicAnalysis();
int topicID = Convert.ToInt32(Request.Form["TopicID"]);
if (tan.TopicAnswers == null)
{
tan.TopicAnswers = new string[15];
}
for (int i = 0; i < Request.Form.Count; i++)
{
string x = Request.Form.Keys[i].ToString();
if (!string.IsNullOrEmpty(x))
{
if (x.Contains("txtA"))
{
tan.TopicAnalysisText = Request.Form[x];
tan.TopicAnalysisTextPending = Request.Form[x];
tan.StatusID = 1;
tan.TopicID = topicID;
tan.AdminUserID = Convert.ToInt32(Request.Form["AdminUserID"]);
tan.TopicAnalysisID = Convert.ToInt32(Request.Form["hiTopicAnalysisID"]);
}
else if (x.Contains("txtQ"))
{
tan.TopicAnalysisText = Request.Form[x];
tan.DateAdded = DateTime.Now;
tan.StatusID = 1;
tan.TopicID = topicID;
TopicAnswer ta = new TopicAnswer();
int qID = GetQuestionNumber(x);
//{TopicAnswerID}
//int aID =
ta.TopicAnswerID = Convert.ToInt32(Request.Form["hiTopicAnswerID"]);
ta.AdminUserID = Convert.ToInt32(Request.Form["AdminUserID"]);
ta.AnswerText = string.Empty;
ta.AnswerTextPending = Request.Form[x];
ta.DateAdded = DateTime.Now;
ta.TopicQuestionID = qID;
ta.TopicAnalysisID = 0;
string swta = cbanc.core.Utility.SerializeObject<TopicAnswer>(ta);
tan.TopicAnswers[i] = swta;
}
}
}
//thisSessionC.BO.AddAnalysis(tan);
XmlData.Append(thisSessionC.BO.GetTopicAnalysis((int)Session["AdminUserID"]).GetXml());
}

有点难以理解您想要做的事情，并且发布的代码存在一些问题。最重要的是处理的性质，这似乎都在一个大根部分。通常，如果您在迭代项目，我们会使用它来梳理它并为我们的元素选择上下文，创建在其他地方查找这些值的变量，等等。但是，我无法理解这些标识符是什么以及应该做什么。例如，你有;
<input type="hidden" id="hiTopicID" name="hiTopicID"
value="{/root/BaseInfo/QueryData/TopicID}" />
但是你的XML输入文件中不存在路径'/ root / BaseInfo / QueryData / TopicID'，因此不确定是什么在查找内容。
然而，我怀疑你所追求的是类似的东西;
<!-- First, just a simple variable as a shortcut for a long path -->
<xsl:variable name="lut" select="/root/BaseInfo/QueryData/TopicID" />
<!-- Then, use it for finding a section with a sub-element of that value -->
<xsl:value-of select="/root/TopicAnalysisbyTopicAnalysisID[TopicID=$lut]/TopicDescription" />
（将TopicDescription替换为您所追求的任何内容）
我仍然认为现在还不清楚，我怀疑你设置XML数据的上下文的方式和XSLT代码并没有帮助你理解如何最好地解决这个问题。使用...是确保流程更好的最佳方法，并且不会陷入过于复杂的输入XML中。
干杯。 ：）
