><P
> XML (eXtensible Markup Language) is a data format for structured
document interchange on the Web. It is a standard defined by
The World Wide Web consortium (W3C). Information about XML and
related technologies can be found at <A

be found at <A
HREF="http://www.jclark.com/xml/"
TARGET="_top"
>http://www.jclark.com/xml/</A
>. The
Makefile that comes with expat does not build a library by
default, you can use this make rule for that:

A source RPM package of expat can be found at <A
HREF="http://www.guardian.no/~ssb/phpxml.html"
TARGET="_top"
>http://www.guardian.no/~ssb/phpxml.html</A
>.
</P
><P
> Note that if you are using Apache-1.3.7 or later, you already
have the required expat library. Simply configure PHP using
<TT
CLASS="option"
>--with-xml</TT
> (without any
additional path) and it will automatically use the expat library
built into Apache.
</P
><P
> On UNIX, run <B
CLASS="command"
>configure</B
> with the <TT
CLASS="option"
>--with-xml</TT
> option. The
<SPAN
CLASS="productname"
>expat</SPAN
> library should be installed
somewhere your compiler can find it. If you compile PHP as a
module for Apache 1.3.9 or later, PHP will automatically use the
bundled <SPAN
CLASS="productname"
>expat</SPAN
> library from Apache.
You may need to set <TT
CLASS="envar"
>CPPFLAGS</TT
> and
<TT
CLASS="envar"
>LDFLAGS</TT
> in your environment before running
configure if you have installed expat somewhere exotic.

PHP's internal representation of the document is always encoded

can not be changed later in the XML parser's lifetime). The
supported source encodings are <TT
CLASS="literal"
>ISO-8859-1</TT

<TT
CLASS="literal"
>US-ASCII</TT

former two are single-byte encodings, which means that each
character is represented by a single byte.
<TT

> can encode characters composed by a
variable number of bits (up to 21) in one to four bytes. The
default source encoding used by PHP is
<TT
CLASS="literal"
>ISO-8859-1</TT
>.
</P
><P
> Target encoding is done when PHP passes data to XML handler
functions. When an XML parser is created, the target encoding
is set to the same as the source encoding, but this may be
changed at any point. The target encoding will affect character
data as well as tag names and processing instruction targets.
</P
><P
> If the XML parser encounters characters outside the range that
its source encoding is capable of representing, it will return
an error.
</P
><P
> If PHP encounters characters in the parsed XML document that can
not be represented in the chosen target encoding, the problem
characters will be "demoted". Currently, this means that such
characters are replaced by a question mark.
