For example. When I parse using SimpleXML, none of the mostix: namespace elements are on show or accessible. Probably a really simple solution, but any ideas guys? Usually, people use children() . $rss = simplexml_load_string(

Why are URLs in XML namespaces?

阅读更多关于 Why are URLs in XML namespaces?

问题 Take this line as just one example: <configuration xmlns:xdt=\"http://schemas.microsoft.com/XML-Document-Transform\"> </configuration> Some brief research has taught me that nothing necessarily has to be hosted at that URL. Therefore, if it\'s just a reference to a namespace contained in a local assembly, why use URLs instead of regular namespaces like the ones typically used by .NET (System.Data, for example)? 回答1: It's just a convention. URIs (which is what they are, not really URLs) are a

XML Namespaces and Unprefixed Attributes

阅读更多关于 XML Namespaces and Unprefixed Attributes

问题 The specification of XML Namespaces explains that the interpretation of unprefixed attributes is determined by the element on which they appear. And that the namespace name for an unprefixed attribute name always has no value. How does this rule apply to the namespace of the attribute jid in the following cases. <query xmlns=\"jabber:iq:roster\"> <item jid=\"romeo@example.com\"></item> </query> If the declaration of the namespace and the attribute in question both don\'t have an prefix, the

问题 My goal is to extract certain nodes from multiple xml files with multiple namespaces using XPath. Everything works fine as long as i know the namespace URIs. The namespace name itself remains constant, but the Schemas (XSD) are sometimes client-generated i.e. unknown to me. Then i am left with basically three choices : use just one schema for the namespace, hoping nothing goes wrong (can i be sure?) get the children nodes of the document and look for the first node with a namespace URI,
