I understand the unreasonableness of many requirements but I don't understand what's happening here. Surely if you transform an XML document to another XML document then any ampersands in the output will still be escaped on serialisation?

Hi,

I have this requirement from a client to retain all the entity references in their xml files after transformation so what i did was collect all the entities in the DTD and then created a character-map for single-character entities. For multi-character ones, i created a used a function to search and replace all occurrences in a text node. My problem is when i use the function and return the value, xslt escapes the ampersand symbol as & and i don't know how i can unescape it without unescaping the real ampersand character.

Below is a snippet of my stylesheet and the output that i'm getting.

XSL:

<!-- character mapping for single-character entities-->
</xsl:character-map>
<!--variable that holds the values of the multi-character entities-->
<xsl:variable name="entityTable" as="element()+">
<entity>
<search>c&#818;h&#818;k&#818;</search>
<replace>&chkeiubareiubareiubar;</replace>
</entity>
<!-- other multi-character entities--> </xsl:variable>

<xsl:sequence select="if (exists($words-to-replace)) then f:replace-all(replace($input, $words-to-replace[1], $replacement[1]),remove($words-to-replace,1),remove($replacement,1)) else $input"/>

<xsl:value-of select="$entityTable[1]/replace" disable-output-escaping="yes"/>
</test>
</xsl:template>
</xsl:stylesheet>
