我最近遇到了一个小小的挑战,而我确实认为很多人只是像往常一样坚持使用-ForEach循环,我试图在外面思考,看看我们有什么替代方法实际上是以相同的方式,但以不同的方式。
在这个XSLT中有另一种实际循环子节点的方法,但是我有点难以真正解决它。我一直在搜索论坛而没有答案,但也许有人可以指出我正确的方向。
我的代码看起来像这个atm:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>Cars</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Name</th>
<th>Model</th>
<th>regyear</th>
<th>price</th>
<th>Description</th>
</tr>
<xsl:for-each select="autoads/ad">
<xsl:if test="type = 2">
<tr>
<td><xsl:value-of select="name"/></td>
<td><xsl:value-of select="model"/></td>
<td><xsl:value-of select="regyear"/></td>
<td><xsl:value-of select="price"/></td>
<td><xsl:value-of select="adtext"/></td>
</tr>
</xsl:if>
</xsl:for-each>
</table>
</body>
</html>
</xsl:template>

我想要做的事情实际上与我对<xsl:for-each select="autoads/ad">
只是没有使用实际的For-Each。
我一直在尝试使用“匹配”功能和模板,然后使用“应用模板”但我无法将其工作,以便值实际上最终作为第一个示例在框中结束:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<h2>Cars</h2>
<xsl:apply-templates select="//ad" />
<table border="1">
<tr bgcolor="#9acd32">
<th>Name</th>
<th>Model</th>
<th>regyear</th>
<th>price</th>
<th>Description</th>
</tr>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="ad">
<td><xsl:value-of select="name" /></td>
<!-- <td><xsl:apply-templates select="autoads/ad/model"/></td> -->
<!-- <td><xsl:apply-templates select="autoads/ad/regyear"/></td> -->
<!-- <td><xsl:apply-templates select="autoads/ad/price"/></td> -->
<!-- <td><xsl:apply-templates select="autoads/ad/adtext"/></td> -->
</xsl:template>
<!-- </table> -->
</xsl:stylesheet>
任何人都有关于如何思考的好建议吗?
答案 0 :(得分:0)
一些提示:
- 首先,建议使用xsl版本2(2007年发布:P)
- 第二,apply-template比for-each更有效,它专门为你想要实现的东西而设计。以下是我将如何在您的代码中使用apply-template:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:template match="/">
<html>
<body>
<h2>Cars</h2>
<table border="1">
<tr bgcolor="#9acd32">
<th>Name</th>
<th>Model</th>
<th>regyear</th>
<th>price</th>
<th>Description</th>
</tr>
<xsl:apply-templates select="/autoads/ad"/>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="/autoads/ad">
<xsl:if test="type = 2">
<tr>
<td><xsl:value-of select="name"/></td>
<td><xsl:value-of select="model"/></td>
<td><xsl:value-of select="regyear"/></td>
<td><xsl:value-of select="price"/></td>
<td><xsl:value-of select="adtext"/></td>
</tr>
</xsl:if>
</xsl:template>
答案 1 :(得分:0)
使用xsl:for-each
没有任何问题 - 但如果您更喜欢使用xsl:apply-templates
,则可以执行以下操作:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/autoads">
<html>
<body>
<h2>Cars</h2>
<table border="1">
<tr>
<th>Name</th>
<th>Model</th>
<th>regyear</th>
<th>price</th>
<th>Description</th>
</tr>
<xsl:apply-templates select="ad[type=2]"/>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="ad">
<tr>
<td>
<xsl:value-of select="name"/>
</td>
<td>
<xsl:value-of select="model"/>
</td>
<td>
<xsl:value-of select="regyear"/>
</td>
<td>
<xsl:value-of select="price"/>
</td>
<td>
<xsl:value-of select="adtext"/>
</td>
</tr>
</xsl:template>
</xsl:stylesheet>
