因表格有固定時間要呈現,使用XML+XSLT(1.0)遇到一個問題,目前想法是在XSLT中先訂好時間透過xsl:for-each 將時間動態的佈道畫面上,但不知道是不是因為XSLT1.0的限制導致畫面無法呈現,程式碼如下:
XSLT:`<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:variable name="times">
<!-- Row 3 -->
<time row="3" cell="1">0015</time>
<time row="3" cell="9">0815</time>
<time row="3" cell="17">1615</time>
<!-- Row 4 -->
<time row="4" cell="1">0030</time>
<time row="4" cell="9">0830</time>
<time row="4" cell="17">1630</time>
</times>
</xsl:variable>
<xsl:template match="/">
<html>
<head>
<title>時間測試</title>
</head>
<style>
@media print
{
table { page-break-after:auto }
tr { page-break-inside:avoid; page-break-after:auto }
td { font-family:DFKai-sb;page-break-inside:avoid; page-break-after:auto }
thead { display:table-header-group }
}
table { page-break-after:auto }
tr { page-break-inside:avoid; page-break-after:auto }
td { font-family:DFKai-sb;page-break-inside:avoid; page-break-after:auto }
thead { display:table-header-group }
</style>
<body style="width:794px; margin: 0 auto;">
<div style="width:650px; margin-left: auto;margin-right: auto;">
<!--內容標題項目-->
<table width="100%" border="0" cellspacing="0" style="margin-top:5px">
<tbody>
<tr>
<td>
<table width="100%" border="1" cellspacing="0">
<tbody>
<!-- 開始生成行 -->
<xsl:call-template name="generate-rows">
<xsl:with-param name="row" select="1"/>
</xsl:call-template>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>
</div>
</body>
</html>
</xsl:template>
<xsl:template name="generate-rows">
<xsl:param name="row"/>
<xsl:if test="$row <= 34">
<tr>
<xsl:call-template name="generate-cells">
<xsl:with-param name="cell" select="1"/>
<xsl:with-param name="row" select="$row"/>
</xsl:call-template>
</tr>
<xsl:call-template name="generate-rows">
<xsl:with-param name="row" select="$row + 1"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
<xsl:template name="generate-cells">
<xsl:param name="cell"/>
<xsl:param name="row"/>
<xsl:if test="$cell <= 24">
<xsl:choose>
<xsl:when test="$row=1 and $cell mod 8=1">
<td style="min-height:20px">日期<br/>時間</td>
</xsl:when>
<xsl:otherwise>
<td style="min-height:20px">
<xsl:value-of select="$times//time[@row=$row and @cell=$cell]"/>
</td>
</xsl:otherwise>
</xsl:choose>
<xsl:call-template name="generate-cells">
<xsl:with-param name="cell" select="$cell + 1"/>
<xsl:with-param name="row" select="$row"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
</xsl:stylesheet>

請問是不是因為XSLT1.0的限制呢?
PS:因排版關係無法將範例呈現好請多見諒

XSLT 1.0 has certain limitations when it comes to dynamically setting and changing variable values because XSLT 1.0 variables are immutable. Once a variable is assigned a value, it cannot be changed or updated. This means that you cannot increment or dynamically adjust the value of a variable within an xsl:for-each loop or other similar constructs.
However, you can achieve dynamic behavior by using recursive templates or by leveraging other XML structures that act as counters or dynamic elements. Here's a basic approach to how you might dynamically display times on the screen using a recursive template:
Example XML
<times>
<time>08:00</time>
<time>09:00</time>
<time>10:00</time>
<time>11:00</time>
</times>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:apply-templates select="times/time" />
</xsl:template>
<xsl:template match="time">
<div>
<xsl:value-of select="." />
</div>
<xsl:if test="following-sibling::time">
<xsl:apply-templates select="following-sibling::time[1]" />
</xsl:if>
</xsl:template>
</xsl:stylesheet>
