XSLT对XML进行数学,逻辑运算(主要是进行分页)?和DELPHIBBS的分页方法不同.YYSUN请看看.(100分)

根据start,range,count分页
XML
-----------------------------
<forum>
<page>
<start>3</start>
<range>2</range>
<count>6</count>
</page>
</forum>
XSL
----------------------
<xsl:choose>
<xsl:when test="forum/page/start&amp;#62;forum/page/range">
<xsl:value-of select="forum/page/start-forum/page/range"/>
</xsl:when>
<xsltherwise>
1
</xsltherwise>
</xsl:choose>
-----------
<xsl:choose>
<xsl:when test="(forum/page/start+forum/page/range)&amp;#60;forum/page/count">
<xsl:value-of select="forum/page/start+forum/page/range"/>
</xsl:when>
<xsltherwise>
<xsl:value-of select="forum/page/count"/>
</xsltherwise>
</xsl:choose>

大于号,小于好已经被&amp;amp;#60;,&amp;amp;#62;替换了,可还不行!!!

数据量小这种办法可以

你的xsl中有两个错误：
１．取元素值必须写成＇／．＇例：(forum/page/start/.)
２．取出来的值为串型，要用Number function进行转换后才能运算．

但是这样forum/page/start我试过也能输出值.
Number function,请帮忙改一下好吗?

你这样写试试，其它的需要运算的地方都用Number函数进行转换
Number(forum/page/start/.)+Number(forum/page/range/.)&amp;lt;Number(forum/page/count/.)
应该是可以的[]

这样也不行!!!
--------------
<xsl:choose>
<xsl:when test="number(forum/page/start/.)&amp;amp;#62;number(forum/page/range/.)">
<xsl:value-of select="number(forum/page/star/.)-number(forum/page/range/.)"/>
</xsl:when>
<xsltherwise>
1
</xsltherwise>
</xsl:choose>

我已经试过了，是行的：
<xsl:choose>
　　<xsl:when test="number(forum/page/start/.)&amp;gt;number(forum/page/range/.)">
　　　　<xsl:value-of select="forum/page/start-forum/page/range/."/>
　　</xsl:when>
　　<xsltherwise>
　　　　1
　　</xsltherwise>
</xsl:choose>

PLEASE SEE THE CODE!!!
