Hi Gertone (since you seem to be the only XML expert in this forum ;-)
What is the best way to include a MAPPING TABLE of special characters (e.g.   => ..160) in XSLT file?
Ciao

Hi go4java,

> since you seem to be the only XML expert in this forum ;-)
well, there are quiet a few others

There are three options for doing what you want,
depending on where you need it

- use the entity resolution mechanism of the parser on the source file
- use the entity resolution mechanism of the parser on the XSLT
- use a lookup table in the XSLT

If you have the   in your source file, you need to have a DOCTYPE declaration
like this
<!DOCTYPE root [
<!ENTITY nbsp "&#160;"/>
]>
<root>.... (with root being your root element)
If not, your XML will not be wellformed, and the XSLT processing cannot start

If you need different mappings, then you can change the resolution values in the ENTITY definitions

If you don't have such a DOCTYPE
and you do have &nbsp; in your source you need to filter them out before hand,
or create the entity definitions

If you have entities like this in your XSLT
you can use the same mechanism on the XSLT
<!DOCTYPE xsl:stylesheet [
<!ENTITY nbsp "&#160;"/>
]>
<xsl:stylesheet....

Note that this is the easiest answer to your question
because the parser solves the problem for you

Cheers!

go4java,

a quick word on lookups

you can have a snippet in your XSLT
that is in a different namespace
(in between templates, or at the end)

eg.

<map:entity source="&nbsp;" result="&#160;" />

and then you can address that this way

document('')//map:entity[@source='&nbsp;']/@result

document('') helps you addressing inside the stylesheet

cheers
