另一个XSLT问题 [英] another XSLT problem
问题描述
您好，
我正在尝试解决XSLT问题，我希望有人可以提供一个
的小指导。我正在将XML转换为HTML。
这里是我正在处理的XML文件的一个例子，大大简化了：
-----------------
< root>
< object name =" a" ;>
< item name =" a1"> Text here< / item>
< item name =" readonlya2"> Text here< / item>
< item name =" a3"> Text here< / item>
< item name =" readonlya4"> Text here< / item>
< item name =" a5"> Text here< / item>
< / object>
< object name =" b">
< item name =" b1"> Text here< / item>
< item name =" b2"> Text here< / item>
< item name =" b3"> Text here< / item>
< item name =" b4"> Text here< / item>
< item name =" b5"> Text here< / item>
< / object>
< / root>
-------------- --------
一个< object> element包含多个< item>元素。我处理每个
< object>另外。
如果< object>不包含只读< item>元素（由
name =" readonly .."标识），我想打印无。在HTML输出中。
如果有一个或多个只读< item>在< object>中，我将显示
那些只读< item> HTML表格中的元素。
看起来很简单，但我尝试过使用一个密钥，一个递归的
模板，以及我能想到的任何其他内容。在将某些内容放入结果树之前，我无法确定
是否为任何只读< item>。
如果我可以设置全局变量从模板中，然后它将很容易检查该变量，以判断是否创建表格
或打印无。但这显然是不可能的。
我错过了什么吗？
谢谢！

Hello,
I''m trying to solve an XSLT problem, and I''m hoping someone can give a
little guidance. I am transforming XML to HTML.
Here''s an example of the XML file I''m dealing with, greatly simplified:
-----------------
<root>
<object name="a">
<item name="a1">Text here</item>
<item name="readonlya2">Text here</item>
<item name="a3">Text here</item>
<item name="readonlya4">Text here</item>
<item name="a5">Text here</item>
</object>
<object name="b">
<item name="b1">Text here</item>
<item name="b2">Text here</item>
<item name="b3">Text here</item>
<item name="b4">Text here</item>
<item name="b5">Text here</item>
</object>
</root>
----------------------
An <object> element contains several <item> elements. I handle each
<object> separately.
If an <object> contains no read-only <item> elements (identified by
name="readonly.."), I want to print "None" in the HTML output.
If there is one or more read-only <item> in an <object>, I will display
those read-only <item> elements in an HTML table.
It seemed simple, but I have tried using a key, and a recursive
template, and anything else I could think of. I can''t find out if there
are any read-only <item>s before putting something in the result tree.
If I could set a global variable from within a template, then it would
be easy to check that variable to tell whether or not to create a table
or print "None." But that is apparently not possible.
Have I missed something?
Thanks!
Mark

你好，
我正在努力解决XSLT问题，我希望有人可以提供一点指导。我正在将XML转换为HTML。

< object name =" a">
< item name =" a1" >这里的文字< / item>
< item name =" readonlya2">这里的文字< / item>
< item name =" a3">这里的文字< / item>
< item name =" readonlya4"> Text here< / item>
< item name =" a5"> Text here< / item>
< / object> ;
< object name =" b">
< item name =" b1"> Text here< / item>
< item name = " b2">文字在这里< / item>
< item name =" b3">文字在这里< / item>
< item name =" b4">文字在这里< ; / item>
< item name =" b5">文字在这里< / item> ;
< / object>
< / root>

< object> element包含多个< item>元素。我处理每个
< object>单独。
如果< object>不包含只读< item>元素（由

使用：
< xsl：stylesheet version =" 1.0"
xmlns：xsl =" http：//www.w3.org/1999/XSL/Transform">
< xsl：output method =" html" />
< xsl：template match =" object">
< xsl：choose>
< xsl：when test =" not（* [starts-with（@ name，''readonly''）]）">
无
< ; / xsl：when>
< xsl：otherwise>
< table>
< xsl：for-each select =" ; * [starts-with（@ name，''readonly''）]">
< tr>< td>< xsl：value-of select =" @ name" ; />< / td>< / tr>
< / xsl：for-each>
< / table>
< / xsl：否则>
< / xsl：选择>
< / xsl：template>
< / xsl：stylesheet>
Use:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:template match="object">
<xsl:choose>
<xsl:when test="not(*[starts-with(@name,''readonly'')])">
None
</xsl:when>
<xsl:otherwise>
<table>
<xsl:for-each select="*[starts-with(@name,''readonly'')]">
<tr><td><xsl:value-of select="@name"/></td></tr>
</xsl:for-each>
</table>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
谢谢！我会检查一下。它适用于我简化的XML文件，
我会看到我对真实内容的看法。
我不知道你可以放一个谓词[...]在星号（*）上，如
* [start-with ... etc]。
Mark
Thank you! I will check this out. It worked on my simplified XML file,
I will see what I get on the real thing.
I didn''t know you could put a predicate [...] on an asterisk (*), as in
*[starts-with...etc].
