[xml] & e & in xml

[Attila]

Salve,

ho un problema con questo carattere. Usando il carattere & all'interno di un documento xml mi appare giustamente l'errore:

The entity name must immediately follow the '&' in the entity reference

Quindi risolvo sostituendo & al carattere &.

Ora però non capisco per quale motivo continua a darmi questo errore se inserisco la seguente stringa:

<html:img src="link.gif" onload="opener.top.mainFrame.location.href='http://www.sito.it/f0?fid=f1&amp;id=ID'">Ti apro la pagina...</html:img>

Più precisamente mi restituisce il seguente errore:
[2008-01-03 13:22:39,531] ERROR: Error while processing response: The reference
to entity "id" must end with the ';' delimiter.

Qualcuno sa dirmi come risolvere?
Ringrazio in anticipo tutti.

P.s. giusto per indicazione il codice è usato all'interno di un documento AIML, ma è pur sempre xml e segue quelle regole. Se inserisco una stringa non contenente il carattere &, funziona tutto regolarmente.

Ho risolto!
Invece di & amp; ho messo
&

Spero che questo servirà a qualcuno

un altro modo per farlo è iunserire uno stylesheet nell'xml e quindi suare il nome delle entità precedute da & commerciale e seguite da ; (un po' come fosse un normale encode per HTML)
esempio:

nel post seguente hai i codici, ma per farteli vedere ho dovuto mettere uno
spazio tra & e #

Ciao a tutti,
scusate se riprendo questo 3D, ma ho lo stesso problema, ma vorrei capire come risolverlo in linea generale, visto che la risposta indicata in precedenza non mi funziona (o non sono capace di implementarla )

Con php creo un file .xml leggendo dei dati in un db e li passo alla funzione GXml di Google Map.

Questi dati possono avere

1) il carattere "&"
2) Altri caratteri particolari (che pero' al momento non posso identificare)
3) formattazione html del tipo, <div style="white-space:nowrap">[b] etc...

Ora, se nel primo caso, sostituendo a "&" la "& # 38 ; # 38 ;" (ho messo gli spazi per poter visualizzare sul forum) funziona, negli altri casi come fare?

Vorrei insomma applicare una regola generale, che credo sia simile a quella indicata da Cimp, ma che non riesco a scrivere.

Qualche suggerimento?

Grazie in anticipo
