Re: Converting ;< ;> to <> in camel

[ski n]

Hi,

Your approach with replaceAll seems valid. It's not uncommon to do it like
that. What is your issue with it? Is it slow or do you don't like the
boilerplate code?

As I can see there are various options:

1) Use processor

Move the processor outside the route into a separate Java class
"UnescapeXML".

Then call it like this:

Processor UnescapeXML = new UnescapeXML ();

And in your route:

.process( UnescapeXML)

2) Use transform

For replacements you can also use transform:

.transform(simple( "${body.replace('&amp;lt;', '<')}"))

3) Use xslt (Saxon)

You may also use xslt-saxon:

https://camel.apache.org/components/next/xslt-saxon-component.html

Then call the following xslt (for example unescape.xsl)

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="3.0">

    <xsl:mode on-no-match="shallow-copy"/>

    <xsl:template match="ciRequestXML">
        <xsl:copy>
            <xsl:copy-of select="parse-xml-fragment(.)"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>


Good luck,

Raymond
