It turned out to be some coding that went bad and produced whitespace before the &lt;?xml declaration. Simple, but so hard to find if you don't know where to look. Thanks for the advice. It is great to know what 'unrecognized input signature' actually means.

Hi there,<br />
<br />
I am using ActiveState Perl and Win32::OLE-&gt;new('Msxml2.DO<wbr />MDocument.<wbr />6.0') along with an xml file. I want to read the contents into an object, which normally works fine, but for some xml files I get 'unrecognized input signature'. Yet these files work fine with say Altova XmlSpy.<br />
<br />
Some browsing on the web leads me to assume that the message hints that not all characters in the file are utf-8. And I assume that MSXML2 is more sensative to this than for instance XmlSpy.<br />
<br />
Can anyone confirm my assumptions? And of course: can anyone suggest how to handle these xml files, so that I can read them properly into MSXML2? Or maybe: how can I detect the characters that cause the issue?

Perl is a high-level, general-purpose, interpreted, dynamic programming languages with over 25 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large-scale development projects.  Perl gained widespread popularity as a Common Gateway Interface (CGI) scripting language, in part due to its regular expression and string parsing abilities. In addition to CGI, Perl is used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications.

Extensible Markup Language (XML) refers to the encoding of documents such that they can be read by both machines and humans. XML documents use tags to show the beginning and end of a set of data. XML is used extensively on websites to show volumes of data, and is the default for a number of office productivity suites. This topic includes discussions of XML-related technologies, such as XQuery (the XML Query language), XPath (the XML Path language), XSLT (eXtensible Stylesheet Language Transformations), XLink (the XML Linking language) and XPointer (the XML Pointer language).
