Stripping non html tags/text from a string

I have a string which I need to send in an xml node to a third party application. That string is then parsed through a html parser over there. The string can have html, but problem occurs with non html tags. For example

<cfset str = "This mail was <b>sent</b> by Jen Myke <jmyke@mail.com> on June 20th.<br/> Click on <a href='http://google.com'>this link</a> for more information.">


There can be non-utf characters too in the string, which also cause issues but I found a old blog post which can help remove non-utf.

<cfset str = reReplace(str, "[^x20-x7E]", "", "ALL")>


But I am unable to figure out how I can remove html look alikes.

Try wrapping the string with encodeForXML(). This should encode any non-ASCII character for use within an XML node.

encodeForXML()

<node>#encodeForXml(str)#</node>

<node>#encodeForXml(str)#</node>

If you need to pass data in an attribute, then

<node attr=#encodeForXmlAttribute(str)#"/>

<node attr=#encodeForXmlAttribute(str)#"/>

Edit: You can try using getSafeHTML() before encoding the rest of the string. This will remove HTML tags from a string using an XML configuration file to set your AntiSamy settings. Check the docs for more info.

AntiSamy

<myTag>stuff</myTag>

Try replacing

< to &lt;
> to &gt;
