    <p>I have a parsing problem that appears when I try to parse from a String, containg a xml, to a org.w3c.dom.Document.</p> <p>Here is a example of a xml String that i'm trying to parse:</p> <pre><code>&lt;enviNFe xmlns="http://www.portalfiscal.inf.br/nfe" versao="2.00"&gt; &lt;idLote&gt;123&lt;/idLote&gt; &lt;NFe xmlns="http://www.portalfiscal.inf.br/nfe"&gt; ... &lt;/NFe&gt; &lt;/enviNFe&gt; </code></pre> <p>The problem is, that after que String had been parsed, by the following code:</p> <pre><code>private Document documentFactory(String xml) throws SAXException, IOException, ParserConfigurationException, DocumentException, TransformerException { DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); factory.setNamespaceAware(true); Document document = factory.newDocumentBuilder().parse( new ByteArrayInputStream(xml.getBytes())); return document; } </code></pre> <p>The tag NFe loads without the namespace (xmlns="http://www.portalfiscal.inf.br/nfe")</p> <p>I want to know why this happens, and what I could do to solve this.</p> <p>Any help will be great. Thanks, and sorry for my english.</p> <p>------EDIT---- For better understanding:</p> <p>This xml will be signed right after de parsing, and will be sent to a Government's server(Brazil). After this, I do another request to this server, to verify if it was processed or not. If it was, I will get a positive response in case of any error. The first problem I had, was that the xml was malformed. This happened because I was sending the xml without that namespace in the tag NFe. To solve this I added it(namespace) right in the File, after the xml had being signed. This problem in fact had been solved, but another occurred: the difference in the signature. Because I signs the xml without the namespace, and send with it.</p>

    1. COside note, don't convert your String back to bytes in order to parse it, use `parse(new InputSource(new StringReader(xml)))`. (otherwise you risk corrupting the xml depending on the default platform character encoding).

    2. COother than my previous comment, your code looks correct. the bug must be elsewhere. can you show the code where you are checking the namespace?

    3. COwell, to check if the namespace is loaded or not, I use this: StringWriter out = new StringWriter(); Transformer xform = TransformerFactory.newInstance().newTransformer(); xform.setOutputProperty(OutputKeys.INDENT, "yes"); xform.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes"); xform.transform(new DOMSource(document), new StreamResult(out)); System.out.println(out.toString());

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
