Adding to DC's response:
2.) What is the difference of the usage of - for example -
"&" and "&"? When do i have to use the one and not the other?
The first is technically an "entity reference", the second is a "character
reference". The only difference is that entities have to be declared in the
DTD, except for the five built-in ones. Numeric character references can be
used without needing a declaration.
3.) And where can i find a good overview of enitites?
I use Bob duCharme's "Annotated XML Specification" - very useful because it
gives the actual text of the specification, then Bob's explanation of what
it really means.
Finally i have also a non-entity question:
I have to replace many of equivalent placeholders in the same
text too. Do i have to nest replace-functions for each of
them in one another like ...
<xsl:value-of select="replace(replace(., '\^12', 'ç'),
'\^13', '&')"/> ... or is there a more elegant solution for this?
As well as DC's solution, another approach is to have a table of
replacements:
<xsl:variable name="mods" as="element(mod)*">
<mod from="\^12" to="ç"/>
<mod from="\^13" to="&"/>
</xsl:variable>
and run through them with a recursive function:
<xsl:function name="f:multi-replace" as="xs:string">
<xsl:param name="in" as="xs:string"/>
<xsl:param name="mods" as="element(mod)*"/>
<xsl:choose>
<xsl:when test="$mods">
<xsl:sequence select="f:multi-replace(
replace($in, $mods[1]/@from, $mods[1]/@to),
subsequence($mods, 2))"/>
</xsl:when>
<xsl:otherwise>
<xsl:sequence select="$in"/>
</xsl:otherwise>
