Problem with Encoding XML entities

[Breton Y. <Y.B...@le...>]

Hello,

I have a problem with the Predefined General Entites of XML (' < 
etc...) and the evaluate function.


Here is my problem:
----------------
1/ I have a XML file with an entity like this:

<ProductColor nameKey="BLEU D&apos;iles"nameKeyType="String"> bla bla 
</ProductColor>


2/ In my DataBase, the stored value is "BLEU D'iles".


3/ When I try to use  the XPath evaluate function as below, it doesn't 
work of course:
$xPath->evaluate("//ProductColor[@nameKey='Bleu d'iles']");

I have also tried :
$xPath->evaluate("//ProductColor[@nameKey='Bleu d&apos;iles']");

It doesn't work too.


My Questions:
------------
I tried to read carefully the documentation but I didn't find anything 
for this. I also tries to use to the decodeEntities function but it's 
only for HTML entities and not XML entities which are not exactly the same.

- Is there a function to evaluate with an automatic XML entities encoding.
- Or did I miss something ?

Thanks !

Yann

Try:
$xPath->evaluate("//ProductColor[@nameKey='BLEU D&apos;iles']");

Sadly XPath does not natively support case insensitivity yet and we haven't
coded a fudge round this hole yet.

Many thanks :o)

Yeah there's another thread going on relating to this kind of thing just
now.  It might be that we support a way to read in the XML file and have
entitites parsed out.  At the moment they go in as is, so hence you have to
search for &apos; rather than '.  Hopefully this is ok for your work to
continue just now.
