-- 关于Xsl控制title提示的问题，急！
1.XML文件类似下面：
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="ConfigSpace.xsl"?>
<set>
<feature_element code="AAAAB" description="Feature description 123" />
<feature_element code="AAAAB" description="Feature description 123" />
<feature_element code="AAAAB" description="Feature description 123" />
<feature_element code="AAAAB" description="Feature description 123" />

<feature_element code="AAAAB" description="Feature description 123" />
</set> 2.xsl 文件： <?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl"
xmlns="http://www.w3.org/TR/REC-html40">
<xsl:script><![CDATA[
var count = 500; //characters number limited.
var flag = true; //flag to decide if show tail string
//Function to return features codes and descriptions
function displayFeature(featureNode)
{
var code = featureNode.selectSingleNode("@code");
var desc = featureNode.selectSingleNode("@description");
count -= code.text.length + desc.text.length + 5; //5: 3 spaces, 1 colon, 1 comma.
if(count>=0)
{
return code.text + " " + ":" + " " + desc.text + ", ";
}
else if(flag)
{
flag = false;
return "There are more features which cannot be displayed here.";
}
else
{
return "";
}
}
]]></xsl:script>
<xsl:template match="/">
<xsl:apply-templates />
</xsl:template>
<xsl:template match="set">
<html>
<script language="javascript">
</script>
<table>
<td class="feature" nowrap="nowrap" >
<xsl:attribute name="colspan"><xsl:value-of select="@colspan" /></xsl:attribute>
<xsl:attribute name="title"
><xsl:for-each select="feature_element"
><xsl:eval>displayFeature(this)</xsl:eval></xsl:for-each
></xsl:attribute>
{...}
</td>
</table>
</html>
</xsl:template>
</xsl:stylesheet> 3.解释，所要实现的是在对应的TD项，鼠标移到上面，则显示相应的title提示。但是每个feature_element都要按code+空格+冒号+空格+description+逗号的形式显示，并尽可能在屏幕上显示满一行后，再换行。从上面的脚本可以看出，它还有字符限制，显示满指定的字符数后，即加一句话There are more features which cannot be displayed here.";这个脚本是我自己实现的。目的基本到，但是：
HTML TD的title属性里的内容，如果包含任一空格，就可能会自动换行，不能在屏幕显示一行后再显示。而要求显示的内容里的空格却不能去掉，另外feature_element的description属性值也可能有空格。目前我找了太多资料也没有方法控制TD的title显示方式，把字符里的空格在脚本里转换成nbsp或 等代码形式，则它会把代码在提示中原样显示，这也不是我们需要的。 哪位高手有什么别的解决方案呀？急死了。另外最好不要用复杂的脚本重新实现TD的 title. [此贴子已经被作者于2008-7-1 12:52:30编辑过]
