问题 Part of my project involves heavy transformations of user-defined schema documents. I need to be able to change target namespaces, support type cross-references and build wsdl upon multiple schema documents. One of the most commonly used operations is changing namespace prefix prior to importing schema into wsdl file. I'm using org.xml.sax.ContentHandler and it's startPrefixMapping method to handle namespaces. All works fine and flawless unless I want to change element types. Here is simple

问题 I'm trying to parse an XML document on Android 2.3.3, but it seems that there is no validating parser. The reason I need validation for is to ignore whitespaces in the XML file (blanks, carriage returns, line feeds, etc.). Thats how I want to parse the document: DocumentBuilderFactory dbfac = DocumentBuilderFactory.newInstance(); dbfac.setValidating(true); dbfac.setIgnoringElementContentWhitespace(true); DocumentBuilder docBuilder; docBuilder = dbfac.newDocumentBuilder(); Document d =
