给出以下 XML： items item nameA/name address0/address start0/start size2/size /item item nameB/name address1/address start2/start size4/size /item item nameC/name address2/address start5/start size2/size /item/items 我想生成以下输
<items>
<item>
<name>A</name>
<address>0</address>
<start>0</start>
<size>2</size>
</item>
<item>
<name>B</name>
<address>1</address>
<start>2</start>
<size>4</size>
</item>
<item>
<name>C</name>
<address>2</address>
<start>5</start>
<size>2</size>
</item>
</items>
我想生成以下输出,包括colspan的
+---------+------+------+------+------+------+------+------+------+ | Address | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | +---------+------+------+------+------+------+------+------+------+ | 0 | | | | | | | A | +---------+------+------+------+------+------+------+------+------+ | 1 | | | B | | | +---------+------+------+------+------+------+------+------+------+ | 2 | | C | | | | | | +---------+------+------+------+------+------+------+------+------+ | 3 | | | | | | | | | +---------+------+------+------+------+------+------+------+------+
我想我可以用一个可变的xslt变量来完成这个,但是,唉,没有这样的事情.
它甚至可能吗？怎么样？
编辑：
还有两个要求：
>也必须有两个项目存在于同一地址
>可能存在空地址,必须在输出中生成
例如：
<items>
<item>
<name>D</name>
<address>0</address>
<start>0</start>
<size>2</size>
</item>
<item>
<name>E</name>
<address>0</address>
<start>3</start>
<size>4</size>
</item>
<item>
<name>F</name>
<address>7</address>
<start>5</start>
<size>2</size>
</item>
</items>
应该产量：
+---------+------+------+------+------+------+------+------+------+ | Address | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | +---------+------+------+------+------+------+------+------+------+ | 0 | | E | | D | +---------+------+------+------+------+------+------+------+------+ | 1 | | | | | | | | | +---------+------+------+------+------+------+------+------+------+ | 2 | | | | | | | | | +---------+------+------+------+------+------+------+------+------+ | 3 | | | | | | | | | +---------+------+------+------+------+------+------+------+------+ | 4 | | | | | | | | | +---------+------+------+------+------+------+------+------+------+ | 5 | | | | | | | | | +---------+------+------+------+------+------+------+------+------+ | 6 | | | | | | | | | +---------+------+------+------+------+------+------+------+------+ | 7 | | F | | | | | | +---------+------+------+------+------+------+------+------+------+
输出格式(text / html)并不重要.
这是修订后的问题的新XSLT 2.0样式表.在我看来它有点难看,但它应该做的工作：<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xsd"
version="2.0">
<xsl:output method="html" indent="yes"/>
<xsl:variable name="cols" as="xsd:integer*"
select="reverse(0 to (max(/items/item/xsd:integer((start + size - 1))) + 1))"/>
<xsl:variable name="addresses" as="xsd:integer*"
select="0 to max(/items/item/xsd:integer(address))"/>
<xsl:template match="/">
<html lang="en">
<head>
<title>Example</title>
</head>
<body>
<xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="items">
<table border="1">
<thead>
<tr>

<xsl:for-each select="$cols">
<th width="100">

</xsl:for-each>

<xsl:variable name="items" as="element(item)*" select="item"/>
<xsl:for-each select="$addresses">

<xsl:value-of select="."/>

<xsl:variable name="cells" as="element(cell)*">
<xsl:for-each select="$items[address = current()]">
<xsl:sort select="xsd:integer(start) + xsd:integer(size)" order="descending"/>
<cell>
<xsl:copy-of select="name"/>
<start><xsl:value-of select="start + size - 1"/></start>
<colspan><xsl:value-of select="size"/></colspan>
</cell>
</xsl:for-each>
</xsl:variable>
<xsl:for-each select="$cols">
<xsl:variable name="cell" select="$cells[start = current()]"/>
<xsl:choose>
<xsl:when test="$cell">
<td colspan="{$cell/colspan}">
<xsl:value-of select="$cell/name"/>
</td>
</xsl:when>
<xsl:when test="$cells[current() < start and current() >= (start - colspan + 1)]"></xsl:when>
<xsl:otherwise>
<td> </td>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>

</xsl:for-each>

</xsl:template>

当将Saxon 9应用于最新的XML输入时,结果如下：
<html lang="en">
