我注意到如果我尝试通过java脚本将更改应用于XSL文件，它只会影响XSL创建的最顶层节点。
实施例： 我想隐藏多个博客条目的所有评论。结果只有顶级博客条目会隐藏评论。
我想更改超链接的文本。超链接文本只会在最顶层的节点中更改。
如何让java脚本影响XSL文件创建的所有节点？

第一篇博文中的变化非常完美。创建一个链接以显示和隐藏评论。但没有其他地方可以工作。

尝试使用generate-id（）函数为A和DIV标记使用唯一ID。
XSLT中的一些更改：
<xsl:for-each select="//entries">
<xsl:sort select="creationTime/@sort" order="descending" />
<!-- define variables -->
<xsl:variable name="unique-id">
<xsl:choose>
<xsl:when test="position() = 1">
<xsl:value-of select="''"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="generate-id(.)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:variable name="comments-id" select="concat('comments',$unique-id)"/>
<xsl:variable name="hideShowLink-id" select="concat('hideShowLink',$unique-id)"/>
<xsl:variable name="a-href" select="concat('javascript:hideShow("',$unique-id,'")')"/>
<!-- title and description -->
<p><xsl:value-of select="creationTime"/>[<xsl:element name="a"><xsl:attribute name="href"><xsl:value-of select="$a-href"/></xsl:attribute> <xsl:value-of select="count(comments)"/> Comments</xsl:element>]</p>
<h1><xsl:value-of select="title"/></h1>
<p><xsl:value-of select="description"/></p>
<br/>
<p>
<xsl:element name="a">
<xsl:attribute name="id"><xsl:value-of select="$hideShowLink-id"/></xsl:attribute>
<xsl:attribute name="href"><xsl:value-of select="$a-href"/></xsl:attribute>
<xsl:attribute name="class"><xsl:value-of select="'comments'"/></xsl:attribute>
Show Comments
</xsl:element>
</p>
<br/><hr/><br/>
<!-- comments -->
<xsl:element name="div">
<xsl:attribute name="id"><xsl:value-of select="$comments-id"/></xsl:attribute>
<xsl:attribute name="class"><xsl:value-of select="'comments'"/></xsl:attribute>
<xsl:attribute name="style"><xsl:value-of select="'display:none'"/></xsl:attribute>
<h2>Comments:</h2>
<xsl:for-each select="//comments">
<p class="comments"><h3><xsl:value-of select="title"/></h3></p>
<p class="comments"><xsl:value-of select="description"/></p>
<p class="comments">-- <xsl:value-of select="creator"/></p>
</xsl:for-each>
<hr/>
</xsl:element>
</xsl:for-each>
您还需要更改JS功能：
function displayResult()
{
var xml=loadXMLDoc("p100993_IR1.2_output_without_header_1.csv.xml");
var xsl=loadXMLDoc("LoadVendorAnalytic.xsl");
// code for IE
if (window.ActiveXObject)
{
var ex = xml.transformNode(xsl);
document.getElementById("entries").innerHTML = ex;
}
// code for Mozilla, Firefox, Opera, etc.
else if (document.implementation.createDocument)
{
var xsltProcessor = new XSLTProcessor();
xsltProcessor.importStylesheet(xsl);
var resultDocument = xsltProcessor.transformToFragment(xml,document);
document.getElementById("entries").appendChild(resultDocument);
}
}
function hideShow(id){
if(document.getElementById("comments"+id).style.display == 'none'){
document.getElementById("comments"+id).style.display = 'block';
document.getElementById("hideShowLink"+id).innerHTML = 'Hide Comments';
} else {
document.getElementById("comments"+id).style.display = 'none';
document.getElementById("hideShowLink"+id).innerHTML = 'Show Comments';
}
}

我编写了自己的示例blogData.xml，我发现了问题：您希望为处理的每个单独的条目元素展开/折叠，但这需要单独的ID并将id传递给hideShow函数。试试这个：
function hideShow(commentsId){
if(document.getElementById(commentsId).style.display == 'none'){
document.getElementById(commentsId).style.display = 'block';
document.getElementById("hideShowLink_" + commentsId).innerHTML = 'Hide Comments';
} else {
document.getElementById(commentsId).style.display = 'none';
document.getElementById("hideShowLink_" + commentsId).innerHTML = 'Show Comments';
}
}
和
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">

<!-- Loops Through all of the entries node in the XML and displays then in order by date descending order -->
<xsl:for-each select="//entries">
<xsl:sort select="creationTime/@sort" order="descending" />
<xsl:variable name="commentsId">comments_<xsl:value-of select="creationTime/@sort"/></xsl:variable>
<p><xsl:value-of select="creationTime"/>

<xsl:attribute name="class">comments</xsl:attribute>

</xsl:for-each>
<hr/>
</xsl:element>
</xsl:for-each>
</div>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
请注意，我为所有元素div和a提供了唯一ID。
请注意，我添加了“隐藏注释”作为按钮的起始值。如果您仍希望在加载时添加值，则必须遍历所有id =“hideShow_ *”元素。
