Why does XStream not respect the encoding in the XML declaration?

XStream - Frequently Asked Questions
XStream architecture is based on IO Readers and Writers, while the XML declaration is the responsibility of XML parsers. XStream all HierarchicalStreamDriver implementation respect the encoding since version 1.3, but only if you provide an InputStream.

Why does XStream not write a XML declaration?

XStream - Frequently Asked Questions
XStream is designed to write XML snippets, so you can embed its output into an existing stream or string. You can write the XML declaration yourself into the Writer before using it to call XStream.toXML(writer). See similar questions...

Why does XStream not write XML in UTF-8?

XStream - Frequently Asked Questions
XStream does no character encoding by itself, it relies on the configuration of the underlying XML writer. By default it uses its own PrettyPrintWriter which writes into the default encoding of the current locale. To write UTF-8 you have to provide a Writer with the appropriate encoding yourself. See similar questions...

What does the XML declaration do? Should I use it?

Code: <?xml version="1.0" encoding="utf-8"?> It tells an XML parser that the document is an application of XML 1.0 and which character encoding it uses. If the encoding is anything other than UTF-8 or UTF-16 you must use the XML declaration, unless the web server sends encoding information in its HTTP headers. Even if it does, you should use the XML declaration, so that the right encoding is specified even if the document is saved to disk and opened locally. See similar questions...

Why does XStream 1.2 no longer read XML generated with XStream 1.1.x?

XStream - Frequently Asked Questions
The architecture in XStream has slightly changed. Starting with XStream 1.2 the HierarchicalStreamDriver implementation is responsible to ensure that XML tags and attributes are valid names in XML, in XStream 1.1.x this responsibility was part of the ClassMapper implementations. Under some rare circumstances this will result in an unreadable XML due to the different processing order in the workflow of such problematic tag names. See similar questions...

How does XStream compare to JAXB (Java API for XML Binding)?

XStream - Frequently Asked Questions
JAXB is a Java binding tool. It generates Java code from a schema and you are able to transform from those classes into XML matching the processed schema and back. Note, that you cannot use your own objects, you have to use what is generated. See similar questions...

How does the character encoding of the XML document affect the parsing performance?

NET Compact Framework Team : .NET Compact Framework version ...
The .NET Compact Framework implements decoders for UTF8, ASCII and UTF16 (big- and little- endian) encodings in managed code. All other encodings, such as all ANSI codepage encodings involve a PInvoke down to the operating system. So using UTF8, ACII and UTF16 is usually faster. If you don't use international characters (outside of the ASCII character set) use UTF8 or ASCII (these have approximately equal performance). Try to avoid using Windows codepage encodings.

Does the scope of an XML namespace declaration include the element it is declared on?

rpbourret.com - XML Namespaces FAQ
For example, in the following, the names B and C are in the http://www.bar.org/ namespace, not the http://www.foo.org/ namespace. This is because the declaration that associates the foo prefix with the http://www.bar.org/ namespace occurs on the B element, overriding the declaration on the A element that associates it with the http://www.foo.org/ namespace. <foo:A xmlns:foo="http://www.foo.org/"> <foo:B xmlns:foo="http://www.bar. See similar questions...

What does extern mean in a function declaration?

Infrequently Asked Questions in comp.lang.c
It refers to a variable which is not actually in your program. For instance, main() { extern int bar; printf("%d\n", bar); return 0; } will compile without errors because bar is declared as being external. (It won't run, though, because you never assign bar a value.) [a] See similar questions...

XStream fails to unmarshal my given XML and I do not know why?

XStream - Frequently Asked Questions
By default XStream is written for persistence i.e. it will read the XML it can write. If you have to transform a given XML into an object graph, you should go the other way round. Use XStream to transfer your objects into XML. If the written XML matches your schema, XStream is also able to read it. This way is much easier, since you can spot the differences in the XML much more easy than to interpret the exceptions XStream will throw if it cannot match the XML into your objects.

XML: How Do I Add A New Encoding To AmphetaDesk?

AmphetaDesk - Frequently Asked Questions
AmphetaDesk 0.93.2 and above ship with a number of default encodings, which you can see by browsing the lib/XML/Parser/Encodings/ directory.

Once you've got the encoding.enc file, drop it into lib/XML/Parser/Encodings/ and test it out on a feed that requires it. See similar questions...

What is the scope of an XML namespace declaration?

rpbourret.com - XML Namespaces FAQ
The scope of an XML namespace declaration is that part of an XML document to which the declaration applies. An XML namespace declaration remains in scope for the element on which it is declared and all of its descendants, unless it is overridden or undeclared on one of those descendants (see questions 4.5, 4.6, and 4.8). For example, in the following, the scope of the declaration of the http://www.foo.org/ namespace is the element A and its descendants (B and C). See similar questions...
