我有以下XSLT：
<xsl:template match="Table">
<tr>
<td>
<font face="Verdana" color="#ffffff" size="2" style="vertical-align: top; white-space: nowrap">
<xsl:value-of select="PRG_DESCRIPTION"/>
</font>
</td>
<td>
<font face="Verdana" color="#ffffff" size="2" style="vertical-align: top; white-space: nowrap">
<xsl:value-of select="DAYS_LEFT"/>
</font>
</td>
<td>  </td>
<xsl:if test="ACTIVE = 0">
<td style="top: 2px">
<form name="myform" onsubmit="popupform(this, 'join');" action="../LogOnSection/SetCourseStart.aspx" method="post">
<input type="hidden" name="CourseID">
<xsl:attribute name="value">
<xsl:value-of select="EEDO_COURSE_ID"/>
</xsl:attribute></input>
<input type="hidden" name="UserID"><xsl:attribute name="value">
<xsl:value-of select="CLI_RID"/>
</xsl:attribute></input>
<input type="hidden" name="EventCode"><xsl:attribute name="value">
<xsl:value-of select="EVE_EVENT_CODE"/>
</xsl:attribute></input>
<input type="hidden" name="DateCreated">
<xsl:attribute name="value">
<xsl:value-of select="DATE_CREATED"/>
</xsl:attribute>
</input>
<input name="Submit" type="submit" value="Go"/>
<br>
</br>
</form>
</td>
</xsl:if>
</tr>
</xsl:template>
我需要做的是读取一个XML文件，并且只显示EVE_EVENT_CODE中不存在XML文件中的代码ID的记录。
XML文件将是这样的：
<?xml version="1.0"?>
<program_codes>
<code id="FUN">CR</code>
<code id="HAN">CR</code>
<code id="AO">CR</code>
<code id="RME">CR</code>
<code id="AD">CR</code>
</program_codes>
XSLT是我甚至不擅长的一件事，我绝望地需要帮助。
更新，修改整张表格
xsl:if是否正确？
<?xml version='1.0' encoding='utf-8'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

这是从数据库中“加载”的方式，GM.AlasData.ActiveOLCourses是一个Web服务函数，它向我们的数据库查询已传递的ParticipantID的活动课程
s = New StringReader(GM.AlasData.ActiveOLCourses(ParticipantID))
xtr = New XmlTextReader(s)
Dim XMLDoc = New XPathDocument(xtr)
Dim XSLTDoc = New XslCompiledTransform
XSLTDoc.Load(Server.MapPath("ListCourseFormat.xslt"))
'Transform XMLDoc and dump HTML results to stringwriter -> sw
XSLTDoc.Transform(XMLDoc, Nothing, sw)
BTW，看起来好像是在使用v1.0
答案 0 :(得分：0)
据我所知，您只想输出那些<Table>元素，其中<EVE_EVENT_CODE>值未在该二级＆＃34; program_codes＆＃34;中提及。 XML文档。
<!-- open extra XML document -->
<xsl:variable name="refDoc" value="document('path/to/program_codes.xml')" />
<!-- collect your IDs from that document -->
<xsl:variable name="refIDs" value="$refDoc/program_codes/code/@id" />
<xsl:template match="/">
<table>
<!-- process only those nodes where the IDs don't match -->
<xsl:apply-templates select="//Table[not(EVE_EVENT_CODE = $refIDs)]" />
</table>
</xsl:template>
<xsl:template match="Table">
<tr>
<td style="font: 12pt Verdana; color: white; vertical-align: top; white-space: nowrap">
<xsl:value-of select="PRG_DESCRIPTION" />

<td style="font: 12pt Verdana; color: white; vertical-align: top; white-space: nowrap">
<xsl:value-of select="DAYS_LEFT" />

<input type="hidden" name="UserID" value="{CLI_RID}" />

提示：
<font>标记并将其从您的记忆中删除。<td>  </td>。编辑在OP发表评论后，我建议采用以下修改后的解决方案：
<!-- open extra XML document -->
<xsl:variable name="refDoc" value="document('path/to/program_codes.xml')" />
<!-- collect your IDs from that document -->
<xsl:variable name="refIDs" value="$refDoc/program_codes/code/@id" />
<xsl:template match="/">
<table>
<xsl:apply-templates select="//Table" />
</table>
</xsl:template>
<xsl:template match="Table">
<!-- effectively: if there's no refID which is contained in the current event code -->
<xsl:if test="count($refIDs[contains(current()/EVE_EVENT_CODE, .)]) = 0">
...
</xsl:if>
</xsl:template>
