I want to ask if there is a way to set up the path where pgmodeler go to find conf folder. That i

Validity error : no DTD found #79

I have a some bug or something similar.

The text was updated successfully, but these errors were encountered:

you need to make the DTD schema files available at:

make install does not copy the files, yet. You can change the schema path by setting the following environment variables:

Hi,
Sorry, but what is «DTD schema files»? I haven’t /usr/local/share/xml/schema/apt-dater dir in my system.

The schema files are schema/*.dtd within the sources. They should be get installed during make install .

And if I don’t want to install apt-dater in my system. Can i just copy this files into property directory on my system? Just without make install .

This will work. The make install for the schema directory just copies the files:

Use the environment variables while running ./configure as quoted above (the paths specified at configure-time are used in apt-dater and the example .xml config files):

There was a missing escape sequence in schema/Makefile.am which has been fixed by 3830e75.

PS: Please provide error messages in LANG=C.

I just can’t understand what a must do to get success result.

But WHY? What happened?

This seems not to be an issue of apt-dater . I’ve referenced the help text twice howto configure the destination of the XML schema files.

In case you get this bug, like I did, the correct answer is that for a while apt-dater has created an XML config without DTD validation, while now it requires it. It has nothing to do with environment variables.

If you used apt-dater during this time, your current configuration file must be adapted.
There are a few other new sections needed to make it run, therefore I suggest you move your current configuration out of the way (mv

Confusing error message following xmllint instructions #240

The CONTRIBUTING docs say to run:

However, when I run this I get the following unhelpful, self-contradictory message:

(Following the online validation instructions, I got no errors.)

The text was updated successfully, but these errors were encountered:

The last line is the one that matters. It can’t find a DTD (which is fine, since we’re using an XSD instead of a DTD), and originally fails to validate because of that. Then it realizes everything’s okay because it has a schema.

I tend to use jing in addition to xmllint since that actually checks the ID/IDREF values.

Should we update the documentation to show that this confusing message actually means «success»?

Yeah, I think including a sample of the expected output and adding a note to ignore the first two lines would be a fine way to go:

Regarding the ID/IDREF values, I was finding that xmllint was also noticing bad values, though it doesn’t seem to notice all bad values, which was strange. I’m not sure I know the pattern of which errors it was able to find and which it wasn’t.

Oh, and better yet would be if xmllint has a flag to make the spurious error go away. I didn’t find one on a quick scan of the help though.

FYI, if I remove —postvalid and just run—

It works without the spurious message and seems to catch errors okay. Is there a case where —postvalid is necessary to catch something? (Here is where I saw an example of checking against an XSD rather than a DTD.)

I’ve been trying to install according to this http://stackoverflow.com/questions/13519203/git-compilingdocumentation-git-add-xml-does-not-validate

I don’t have brew or fink, so I installed http://www.linuxfromscratch.org/blfs/view/cvs/pst/xmlto.html by hand doing the steps for docbook-xml-4.5, docbook-xsl-1.79.1, and libxslt-1.1.29. I built dblatex-0.3.9 and asciidoc-8.6.9 from source.

I installed the catalog stuff in /usr/local/etc/xml/catalog and /usr/local/etc/xml/docbook, updated the $XML_CATALOG_FILES env. Running ‘xmllint —help’ it said it looks in /etc/xml/catalog by default so I made that a symbolic link to my /usr/local/etc/xml/catalog just in case.

$ ls -l /etc/xml/catalog

  • Question

  • I have a process that generates an XML file that I need to then validate against a DTD. Since the XML file is a fragment of a larger document, the XML file cannot have a DOCTYPE within it.

    The code to open and try to validate is:

    Code Snippet

    XmlReaderSettings xmlSetting = new XmlReaderSettings();
    xmlSetting.ProhibitDtd = false;
    xmlSetting.ValidationType = ValidationType.DTD;
    xmlSetting.ValidationEventHandler += new ValidationEventHandler(ValidationCallback);

    string strFile = «8091000000024.xml»;

    {
       XmlReader xmlread = XmlReader.Create(strFile, xmlSetting, xmlParser);
       while (xmlread.Read()) 
       {
       }

       xmlread.Close();
    }

    The ValidationCallback is a simple function that stores the validation error in a string.

    The start of the XML is

    Code Snippet

    <?xml version=»1.0″ encoding=»UTF-8″?><servinfo id=»8091000000024″ refid=»9100″><title>DESCRIPTION</title>…

    Yes I know that IDs have to start with a letter. I need help in getting the validation working. Also I do not own the DTD so changing it to a schema is not an option.

    When above code is used, I get «No DTD found.». If I remove «file:///C:/projects/Cllc/SVGWebsite/validationTestHarness/bin/Debug/j2008.dtd» and insert a DOCTYPE in the XML file the parsing works.

    If I have both the «file:///C:/projects/Cllc/SVGWebsite/validationTestHarness/bin/Debug/j2008.dtd» and insert the DOCTYPE, I get an error about having two DOCTYPE is invalid.

    Any ideas on how to get this to work or why this is not possible?

  • Hi Jason,

    I’ve been working on this problem myself, I used the following code;

    Code Snippet

                XmlReaderSettings settings = new XmlReaderSettings();

                settings.ProhibitDtd = false;
                settings.ValidationType = ValidationType.DTD;
                settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallback);

                XmlReader myxmlr;
                myxmlr = XmlReader.Create(«BasisOption.xml», settings);

                try
                {
                    bool result = myxmlr.Read();

                              }
                catch (Exception ex)
                {
                    UtilException.DumpException(ex);
                }

    However the key to making this work was the following line in the xml.

    <!DOCTYPE root-element SYSTEM «validation.dtd»>

    Without this line I too got the very unhelful ‘No DTD found.»

    Cheers

I too am having trouble with stuff in my DTD not being recognized.

I am very new to XML and am just trying to do the exercises in a book.

On the below XML, I get the error «Entity danny-description not defined».

I also tried adding the following line to the catalog file:

Я пытаюсь использовать xmllint для проверки моей работы при разработке базовой схемы XSD, т. е. схемы XML. Однако это дает мне ошибку

ошибка проверки: DTD не найден.

что я делаю не так?

моя команда xmllint:

xmllint --noout --valid --schema simple.xsd lucas-basic.xml
lucas-basic.xml:5: validity error : Validation failed: no DTD found !
        >
        ^
lucas-basic.xml validates

тестовый файл XSD:

<?xml version = "1.0" encoding = "UTF-8"?>
<!--Generated by XML Authority. Conforms to w3c http://www.w3.org/2001/XMLSchema-->

                        </xsd:sequence>
                </xsd:complexType>

        <nickname>Wee Beastie</nickname>
        <nickname>Count Zero</nickname>

URL в xsi: noNamespaceSchemaLocation возвращает вышеуказанный XSD. Кроме того, я загрузил файл xsd и поместил его в текущий каталог в качестве дополнительной меры, но это, похоже, ничего не изменило.

--valid для DTDs, не XSDs.

это будет работать для вас, вместо:

xmllint --noout --schema http://lucas.ucs.ed.ac.uk/xml-schema/xmlns/simple.xsd lucas-basic.xml

попытка OP и принятый ответ «проверяют» XSD, проверяя его на примере файла. Для проверки xsd-файла на соответствие спецификации XSD может использоваться следующая команда:

xmllint --noout --schema http://www.w3.org/2001/XMLSchema.xsd my_schema.xsd

… и для v1.1 Схема https://www.w3.org/2009/XMLSchema/XMLSchema.xsd

Примечание: v1.0 schema имеет некоторые квалификации в верхней части схемы нормативной структуры, поэтому возможно, что на самом деле должен использоваться другой файл, но это сработало хорошо для меня.
