These entities are declared in the document's Document Type Definition (DTD). You should use the numerical Unicode version of the

I'm new with python and especially with Biopython. I'm trying to take some information from an XML file with Entrez.efetch and then read it. Last week this script worked well: handle = Entrez.efetch(db="Protein", id="YP_008872780.1", retmode="xml") records = Entrez.read(handle) But now I'm getting an Error: > Bio.Entrez.Parser.ValidationError: Failed to find tag 'GBSeq_xrefs' in the DTD. To skip all tags that are not represented in the DTD, please call Bio.Entrez.read or Bio.Entrez.parse with validate=False. So I run this: records = Entrez.read(handle, validate=False) But I'm still getting an

XML: How to load the contents of one xml file into another

阅读更多关于 XML: How to load the contents of one xml file into another

I would just like to be able to dynamically write the contents of an xml file from another xml file. A.XML contains: <?xml version="1.0"?> <node> -Include Contents of b.xml </node> B.XML contains: <anode> a </anode> is there any way to do this in xml? End product looks like this: <?xml version="1.0"?> <node> <anode> a </anode> </node> Update from comments : In xml alone. so that when i view the xml file in a browser it renders correctly Use an external (parsed) general entity to reference b.xml from a.xml . <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE node [ <!ENTITY b SYSTEM "b.xml"> ]>

Check for malicious XML before allowing DTD loading?

阅读更多关于 Check for malicious XML before allowing DTD loading?

Since libxml 2.9, loading external entities has been disabled when parsing XML, to prevent XXE attacks . In that case, to be able to load a DTD file when parsing the XML with PHP's DOMDocument, LIBXML_DTDLOAD must be specified. What would be a good way to verify that only the expected DTD will be loaded, before enabling LIBXML_DTDLOAD ? One approach I can think of (as shown in the example code below) would be to keep entity loading disabled, parse the XML file once, check that the DOCTYPE declaration is as expected, then parse the XML again with entity loading enabled. Would that be sufficient

Why use both XSD and DTD for XML?

阅读更多关于 Why use both XSD and DTD for XML?

问题 Stackoverflow has a couple of great questions contrasting XSD and DTD and choosing between XSD and DTD. But I came across a data format and library that used both XSD and DTD. The XML documents specify the DTD but the supporting library requires the XSD to encode and decode. What are the benefits of using an XSD and DTD at the same time? 回答1: The most significant time I've seen both DTD and XSD used together relates to the example you cite: A sector standards group had defined their XML

Local XML validation with DTD or XSD using a relative path?

阅读更多关于 Local XML validation with DTD or XSD using a relative path?

问题 An XML file can be defined and validated with an Document Type Description (DTD) or XML Schema (xsd) as follows: <?xml version='1.0' encoding='UTF-8'?> <annotation xmlns="http://www.xyz.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.xyz.com file:system.xsd" > or <?xml version='1.0' encoding='UTF-8'?> <!DOCTYPE annotation SYSTEM "http://www.xyz.de/system.dtd"> Both ways define a URL where the DTD or XSD is found. Is there a way to give a relative or

Parsing XHTML with DTD using XDocument

阅读更多关于 Parsing XHTML with DTD using XDocument

I need to get plain text from XHTML documents. I am sure I already read somewhere here, that XDocument on WP7 does not support DTD. I cannot find it though. Well, when I try to parse XHTML with DTD using XDocument, it throws NotSuportedException. Last call in stacktrace is at System.Xml.XmlTextReaderImpl.ParseDoctypeDecl() . That is exactly same even if I try to use some dummy XmlResolver - it doesn't really get called. (following answer in this question ). So I assume that WP7 really doesn't support it. Well, I need to parse XHTML docs. So far I came up with two (more or less real) solutions:

问题 I'm trying to use xmltask for ant to modify a file in a subdirectory: project/path/to/file.xml The file refers to a DTD like this: <!DOCTYPE data SYSTEM "mydtd.dtd"> I don't have the flexibility to change these documents. This DTD is stored in the same subdirectory, which has always worked fine: project/path/to/mydtd.dtd Unfortunately, xmltask is trying to locate the dtd in my project's top-level directory, which is where my build file is located, and where I run from: [xmltask] java.io
