如何在使用ColdFusion函数XMLFormat（）时转义HTML字符实体？ [英] How can I escape HTML character entities when using ColdFusion function XMLFormat()?

问题描述

我有以下HTML块：

<p>The quick brown fox jumps over the lazy dog &mdash; The quick brown fox jumps over the lazy dog.</p>
<p>The quick brown fox jumps over the lazy dog &mdash; The quick brown fox jumps over the lazy dog.
<br>The quick brown fox jumps over the lazy dog &mdash; The quick brown fox jumps over the lazy dog.

这是无效的XHTML。但是，我需要将此HTML包含在XML文档中。我尝试使用 XMLFormat（），以便将< 转换为& lt; 和> 到& gt; 不幸的是，它还会将& mdash; 转换为& amp; mdash;

It is NOT valid XHTML. However, I need to include this HTML in an XML document. I tried using XMLFormat() in order to convert the < to < and the > to >, which works great. Unfortunately, it also converts — to —, which is not valid and throws an exception in the CFXML tag.

<cfxml variable="myXML">
    <content>#XMLFormat(myHTML)#</content>
</cfxml>

解决方案

您有几个选项。很多取决于如何使用这些内容。这将非常有帮助，包括一个所需的输出文档，以及指示这个xml的使用位置。

You have a few options. A lot depends on how this content is going to be used. It would be extremely helpful to include a desired output document, as well as indicate where this xml is being used.

如果你不想搞乱的内容您可以随时使用 CDATA ，例如：

If you don't want to mess with the content of the HTML at all, you could always use CDATA, like this:

<cfxml variable="myXML">
    <content><![CDATA[#myHTML#]]></content>
</cfxml>

此外，我知道你说你不想转换剩余的和号，看看这是怎么回事。 HTML内容是您要处理的字符串 - 在这种情况下，应该对其进行转义，以便以后可以将其解除转义，或者您希望将其作为文档的一部分的有效XML。我的意思是，稍后处理< content> 标签的内容时，如果&符号没有转义，您将遇到问题。

Also, I know you say you don't want to convert the remaining ampersands but I just don't see how this is so. Either the HTML content is a string you want to process -- in which case, all of it should be escaped so that it can be unescaped later -- or it's valid XML that you want to be part of the document. I mean, when you process the contents of the <content> tag later on, you will run into problems if the ampersands aren't escaped.
