dtd

问题 I have looked at many examples for validating an XML file against a DTD, but have not found one that allows me to use a proxy. I have a cXml file as follows (abbreviated for display) which I wish to validate: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE cXML SYSTEM "http://xml.cxml.org/schemas/cXML/1.2.018/InvoiceDetail.dtd"> <cXML payloadID="123456" timestamp="2009-12-10T10:05:30-06:00"> <!-- content snipped --> </cXML> I am trying to create a simple C# program to validate the xml

问题 Trying to achieve something like this ATTLIST employee role (leader|analyst|leader,analyst) where I can't change it into an element; it needs to be an attribute. It seems like DTD doesn't like commas in its expressions. 回答1: An attribute in XML cannot contain elements. You're really going against the grain to try to add structure to attributes in any way. If you must do it, keep it simple: You can represent a list via space or comma-separated values. Going any further runs into requiring a

问题 I'm trying to generate cXML classes for version cXML 1.2.034 as per http://cxml.org/ XSD (converted by visual studio). I converted the cXML.dtd to xsd. Then Tried running: xsd.exe cXML.xsd /c /language:CS /n:MyNamespace But it threw an error: Error: Error generating classes for schema 'cXML'. - The element 'uri:ds:Signature' is missing. Then I found this issue here: Generating C# classes from XSD which seems relevant. So I downloaded xmldsig-core-schema.xsd from http://www.w3.org/TR/xmldsig

问题 I'm using the MathML DTD for parsing MathML using System.Xml.Linq. While the ordinary MathML stuff gets recognized fine, the MMLEXTRA include in the DTD gets ignored and I get errors. Here's the code I'm using: if (!string.IsNullOrWhiteSpace(mathML)) { try { const string preamble = "<!DOCTYPE mml:math PUBLIC \"-//W3C//DTD MathML 2.0//EN\"\n" + "\"http://www.w3.org/Math/DTD/mathml2/mathml2.dtd\" [\n" + "<!ENTITY % MATHML.prefixed \"INCLUDE\">\n" + "<!ENTITY % MATHML.prefix \"mml\"> \n" + "]>";

问题 I am new to XML and DTD. I have written an XML file with DTD. Here is it. <?xml version="1.0"?> <!DOCTYPE note[ <!ELEMENT note (page , author ,company)> <!ELEMENT page (#PCDATA)> <!ELEMENT author (#PCDATA)> <!ELEMENT company (#PCDATA)> <!ATTLIST note type CDATA #IMPLIED> ]> <note typ="single"> <page>1000</page> <author>devan</author> <author>devan</author> <company>IDM</company> </note> It works fine. But my problem is, if you set the note attribute as typ it displays the result in the web

问题 I am struggling with this question. Could I, using XSLT, generate an XSD based on an XML file input ? I know there are many software that I can use to do that automatically, but I need it by writing code. Could you help me with how to start in this and support me with useful resources? This is a sample XML file: I need to generate XSD using XSLT and validate it: <test> <a> <b> </b> </a> <d> </d> </test> 回答1: As Marcus observed in the comments, there are many degrees of freedom, but here's a

问题 I am trying to validate metadata.xml against www.gentoo.org/dtd/metadata.dtd with xmllint from =dev-libs/libxml2-2.9.3 ebuild. I tried the commands (some from here): $ xmllint --noout --valid metadata.xml error : Unknown IO error metadata.xml:2: warning: failed to load external entity "http://www.gentoo.org/dtd/metadata.dtd" the same for xmllint metadata.xml --dtdvalid metadata.dtd and xmllint --loaddtd http://www.gentoo.org/dtd/metadata.dtd $ xmllint --valid metadata.xml --schema metadata

问题 I have this XML along with an embedded DTD: <?xml version="1.0" ?> <!DOCTYPE customers [ <!ELEMENT customers (name,age,roll,sex)> <!ELEMENT name (#CDATA)> <!ELEMENT age (#CDATA)> <!ELEMENT roll (#CDATA)> <!ELEMENT sex (#CDATA)> ]> <customers> <name>XYZ</name> <age>19</age> <roll>23</roll> <sex>M</sex> </customers> When i try to validate the XML, its showing me an error. But if i change the #CDATA to #PCDATA then the validation is successful. Question 1) I don't have a proper explanation why

问题 I read Extensible Markup Language (XML) 1.0 (Fifth Edition) W3C Recommendation 26 November 2008 3.2 Element Type Declarations has: An element type declaration takes the form: Element Type Declaration elementdecl ::= <!ELEMENT Name contentspec > contentspec ::= 'EMPTY' | 'ANY' | Mixed | children And in 3.2.1 Element Content has: Element-content Models children ::= (choice | seq) ('?' | '*' | '+')? cp ::= (Name | choice | seq) ('?' | '*' | '+')? choice ::= '(' S? cp ( S? '|' S? cp )+ S? ')' seq

问题 Is it legal for an XML document to specify that it follows both a DTD and a Schema? Won't the two conflict with one another? 回答1: Technically I think you would have problems with the DTD not recognizing the attributes for referencing the schema (the namespace declaration and the schema location). However I think it depends on how you're validating your XML and whether or not you can ignore the DTD for validation if a schema is specified. Also, for your assignment are you sure you have to
