从XSL中的CDATA标记内渲染HTML标记 [英] Rendering HTML Tags from within CDATA tag in XSL

问题描述

我的XML代码中有一个CDATA标记，其中包含一些超链接。

 < smartText><！[CDATA [
在单个股票中，S股涨幅最大。 & P。 500是
< a href =’http：//investing.domain.com/research/stocks/snapshot 
 /snapshot.asp?ric=LNC’&Lincoln National Corp< / a>和
< a href ='http：//investing.domain.com/research/stocks/snapshot 
 /snapshot.asp?ric=PLD'>ProLogis</a>]]]> ; 
< / smartText> 
  

我正尝试将其转换为HTML页面，如下所示...

 < p class = smartText> 
< xsl：copy-of select = marketSummaryModuleData / smartText /> 
< / p> 
  

不幸的是，页面上的输出显示为纯文本，而不是html。

$在个别股票中，标普500指数成份股中涨幅最大的股票是标准普尔指数。 500是< a href =’http：//investing.businessweek.com/research/stocks/snapshot/snapshot.asp？ric = PLD’> ProLogis< / a>和< a href =’http：//investing.businessweek.com/research/stocks/snapshot/snapshot.asp？ric = LNC’&Lincoln National Corp< / a>。

CDATA部分是从经典ASP页面创建的，因此实际的XML输出不包含CDATA部分。这可能是问题的一部分吗？我似乎无法获取要在页面上呈现的信息。我尝试了Google搜索提供的多种解决方案，例如disable-escape-tags，xsl：copy-of，xsl：value-of等。

谢谢

解决方案

您必须更正XML，以便所需的HTML（并且它必须是格式正确的XML）

任何CDATA部分都只是text（）节点的一部分，XSLT处理器将其视为此类。

p>

在CDATA中添加标记是公认的不良做法，并且所报告的问题是一种典型的结果。

DOE（禁用-output-escaping）是XSLT中的一项可选功能，并不能保证在不同的XSLT处理器上实现并产生相同的预期结果。

引用 W3C XSLT规范 。：

b
$ b

不需要XSLT处理器支持端口禁用输出转义。如果xsl：value-of或xsl：text指定应禁用输出转义，并且XSLT处理器不支持此功能，则XSLT处理器可能会发出错误信号；否则，将显示错误消息。如果它不表示错误，则必须通过不禁用输出转义来恢复。


和：

由于禁用输出转义可能不适用于所有XSLT处理器，并且可能导致XML格式不正确，因此仅在没有其他选择时才应使用它。

I have a CDATA tag within my XML code which contains some hyperlinks.

<smartText><![CDATA[
Among individual stocks, the top percentage gainers in the S.&P. 500 are
<a href ='http://investing.domain.com/research/stocks/snapshot
/snapshot.asp?ric=LNC'>Lincoln National Corp</a> and 
<a href ='http://investing.domain.com/research/stocks/snapshot
/snapshot.asp?ric=PLD'>ProLogis</a>.]]>
</smartText>

I am trying to transform it into an HTML page as follows...

<p class="smartText">
    <xsl:copy-of select="marketSummaryModuleData/smartText"/>                                    
</p>    

Unfortunately the output onto the page shows up in pure text, not as html.

Among individual stocks, the top percentage gainers in the S.&P. 500 are <a href ='http://investing.businessweek.com/research/stocks/snapshot/snapshot.asp?ric=PLD'>ProLogis</a> and <a href ='http://investing.businessweek.com/research/stocks/snapshot/snapshot.asp?ric=LNC'>Lincoln National Corp</a>.

The CDATA section is being created from a classic ASP page, so the actual XML output does not contain the CDATA section. Could that be part of the problem? I cannot seem to get the information to render on the page. I have tried multiple solutions offered up by Google searches, such as disable-escape-tags, xsl:copy-of, xsl:value-of and more.

Thank you

You have to correct the XML so that the desired HTML (and it needs to be well-formed XML) is not contained within a CDATA section.

Any CDATA section is just part of a text() node and the XSLT processor treats it as such.

Putting markup within CDATA is universally acknowledged as bad practice and the reported issue is one typical result.

DOE (disable-output-escaping) is an optional feature in XSLT and is not guaranteed to be implemented and producing the same expected results on different XSLT processors.

To quote the W3C XSLT Spec.:

"An XSLT processor is not required to support disabling output escaping. If an xsl:value-of or xsl:text specifies that output escaping should be disabled and the XSLT processor does not support this, the XSLT processor may signal an error; if it does not signal an error, it must recover by not disabling output escaping. "

and:

"Since disabling output escaping may not work with all XSLT processors and can result in XML that is not well-formed, it should be used only when there is no alternative."
