我试图将一个节点序列呈现为M x N表，并根据这里已经问到的另一个问题来管理它。
现在，我尝试将子序列呈现为内部M x N表。
<?xml version="1.0" encoding="UTF-8"?>
<root>
<item id="1">
<subitem>1.1</subitem>
<subitem>1.2</subitem>
<subitem>1.3</subitem>
<subitem>1.4</subitem>
</item>
<item id="2">
<subitem>2.1</subitem>
<subitem>2.2</subitem>
<subitem>2.3</subitem>
<subitem>2.4</subitem>
<subitem>2.5</subitem>
</item>
<item id="3">
<subitem>3.1</subitem>
<subitem>3.2</subitem>
<subitem>3.3</subitem>
<subitem>3.4</subitem>
</item>
<item id="4">
<subitem>4.1</subitem>
<subitem>4.2</subitem>
<subitem>4.3</subitem>
</item>
</root>
以及相应的XSL：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" indent="yes"/>
<xsl:key name="items-by-row" match="root/item"
use="floor(count(preceding-sibling::item) div 2) + 1"/>
<xsl:key name="subitems-by-row" match="root/item/subitem"
use="floor(count(preceding-sibling::subitem) div 2) + 1"/>
<xsl:template match="subitem" mode="cell">
<subitem>
<xsl:value-of select="current()" />
</subitem>
</xsl:template>
<xsl:template match="subitem" mode="row">
<subitem-row>
<xsl:apply-templates select="key('subitems-by-row', position())" mode="cell"/>
<xsl:variable name="span" select="2 - count(key('subitems-by-row', position()))"/>
</subitem-row>
</xsl:template>
<xsl:template match="item" mode="cell">
<td>
<item>
<xsl:value-of select="current()/@id" />
</item>
<xsl:apply-templates select="./subitem[position() mod 2 = 1]" mode="row"/>
</td>
</xsl:template>
<xsl:template match="item" mode="row">
<tr>
<xsl:apply-templates select="key('items-by-row', position())" mode="cell"/>
<xsl:variable name="span" select="2 - count(key('items-by-row', position()))"/>
</tr>
</xsl:template>
<xsl:template match="/">
<html>
<body>
<table>
<xsl:apply-templates select="//item[position() mod 2 = 1]" mode="row"/>
</table>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
导致以下输出：
<?xml version="1.0" encoding="UTF-8"?>
<html>
<body>

我如何才能仅获取相应项目的子项目？
brgds，伯特
只需对subitem模板进行少量更改即可。尝试：
<xsl:template match="subitem" mode="row">
<xsl:variable name="item" select=".." />
<subitem-row>
<xsl:apply-templates
select="key('subitems-by-row', position())[../@id = $item/@id]" mode="cell"/>
<xsl:variable name="span" select="2 - count(key('subitems-by-row', position()))"/>
</subitem-row>
</xsl:template
具有以下（希望如此）输出：
<html>
<body>
<table>
<tr>
<td>
<item>1</item>
<subitem-row>
<subitem>1.1</subitem>
<subitem>1.2</subitem>
</subitem-row>
<subitem-row>
<subitem>1.3</subitem>
<subitem>1.4</subitem>
</subitem-row>
</td>
<td>
<item>2</item>
<subitem-row>
<subitem>2.1</subitem>
<subitem>2.2</subitem>
</subitem-row>
<subitem-row>
<subitem>2.3</subitem>
<subitem>2.4</subitem>
</subitem-row>
<subitem-row>

</tr>

<subitem>3.2</subitem>
</subitem-row>

<subitem>3.4</subitem>
</subitem-row>
</td>
