'' question

... hi all,

just a question about the '' character.

My application parses some xml files using the
xmlParseFile() API.
This API gives an error if the file has the following
content:
<content>Asl&#x10;URP</content>

What I have to do to parse files like that?

TIA

The XML standard defines a character as

 Char ::= #x9 | #xA | #xD |
          [#x20-#xD7FF] | [#xE000-#xFFFD] |
[#x10000-#x10FFFF]

(http://www.w3.org/
TR/xml/#charsets)

As such the entity corresponding to codepoint 0x10 is not a
valid
character according to the XML standard, and a conforming
parser will
not allow it in a document.

So it seems the content is binary, in which case it should
either be
encoded in some way (base64 for example), or not be in XML
at all (XML
is not a binary transport).

As indeed it should, character 0x10 (hexadecimal, ie.
decimal 16,
i.e. ASCII DLE, Data Link Escape, control-P) is not legal in
XML 1.0
documents.

You can use XML 1.1 if your tools support it, but it's more
likely
an error in the data.  Maybe it's intended to be a newline,
which
would be &#10; instead, or in hexadecmial &#xa;, or
maybe you have
a character set problem and it's supposed to be some
accented
character, in which case you need to convert to UTF-8 (for
example)
*before* escaping non-ascii characters.
