I have below xml. Namespace is missing in the below xml.
<?xml version="1.0" encoding="UTF-8"?>
<policy>
<num-drivers>123</num-drivers>
<risk-policy-ind>false</risk-policy-ind>
<premium-amt>23.00</premium-amt>
</policy>
Looking for java code to take the above xml as input and add namespace (xmlns) element to it? The expected output xml is as below:
<?xml version="1.0" encoding="UTF-8"?>
<policy xmlns="http://aaa.bbb.com">
<num-drivers>123</num-drivers>
<risk-policy-ind>false</risk-policy-ind>
<premium-amt>23.00</premium-amt>
</policy>
First of all, in the above xml, risk-policy-ind tag is not properly closed. In XML all tags are custom tags, they should close. Moreover,in xml, tags are performed without namespace.
If u just want to add xmlns attribute to policy tag, create policy element using w3c.dom.Element and set attribute using setAttribute function

I am trying to append an element to my xml document so it looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<students>
</students>
However, it ends up looking like this:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<students/>
This is the code I am using:
// results is the new XML document I created using DocumentBuilder.newDocument();
Element root = results.createElement("students");
results.appendChild(root);
How come it isn't looking like how I want it to?
Java dom is implemented based on the xml specification, and by definition: An element with no content is said to be empty : https://www.w3.org/TR/REC-xml/#sec-starttags.
I have this XML:
<Body xmlns:wsu="http://mynamespace">
<Ticket xmlns="http://othernamespace">
<Customer xlmns="">Robert</Customer>
<Products xmlns="">
<Product>a product</>
</Products>
</Ticket>
<Delivered xmlns="" />
<Payment xlmns="">cash</Payment>
</Body>
I am using Java to read it as a DOM document. I want remove the empty namespace attributes (i.e., xmlns=""). Is there any way to do that?
You need to understand that xmlns is a very special attribute. Basically, the xmlns="" is so that your Customer element is in the "unnamed" namespace, rather than the http://othernamespace namespace (and likewise for other elements which would otherwise inherit a default namespace from their ancestors).
If you want to get rid of the xmlns="", you basically need to put the elements into the appropriate namespace - so it's changing the element name. I don't think the W3C API lets you change the name of an element - you may well need to create a new element with the appropriate namespaced-name, and copy the content. Or if you're responsible for creating the document to start with, just use the right namespace.
I have a simple XML document that is flagged (correctly) in Eclipse as having no grammar. I use the file to preload a database on initialisation. Is there a "generic" DTD or Schema that I could apply to this document (and similar - I have over 15 of them) to eliminate this warning and be more correct in my XML structure?

<AbnormalFlag>

<description>High</description>

Just add this on top of your xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
i need to parse a XML file that looks like this
1.<?xml version="1.0" encoding="UTF-8"?>
2.<Root>
3.<Record>
4.<in><![CDATA[<?xml version="1.0" encoding="UTF-8"?><XML><Attribute AttrID="A">Test</Attribute>-<Attribute AttrID="B"> <![CDATA[Aap Noot Mies]]> </Attribute>]]></XML></in>
5.<out><![CDATA[]]></out>
6.</Record>
7.</Root>
I am getting a erro while parsing line number 4 Is there any way to escape a CDATA end token ( ]]> ) within a CDATA section in an xml document.
Your input is not well formed there are several errors I think you need to fix whatever generated that to generate something more like
<?xml version="1.0" encoding="UTF-8"?>
<Root>
<Record>
<in><![CDATA[<?xml version="1.0" encoding="UTF-8"?><!-- - --><XML><Attribute AttrID="A">Test</Attribute>-<Attribute AttrID="B"> <![CDATA[Aap Noot Mies]]<![CDATA[> </Attribute></XML>]]></in>
<out><![CDATA[]]></out>
</Record>
</Root>
Note that the outer CDATA needs <![CDATA[ not <!CDATA[ the first use of ]]> needs to be quoted (for example by stopping and starting the outer CDATA section as here). The outer ]]> needs to be moved after the </XML> so that the end as well as the start of the element is quoted.
That makes the file technically well formed, although elements with name XML (or in general starting with xml in upper or lower case are reserved by the W3C for use in XML related specifications and should not be used in user XML files unless it is a specific element or attribute (such as xmlns defined by the W3C)
In addition I added a (quoted) comment around the dash after the XML declaration as if that CDATA section were extracted and made into an XML document it would make the resulting document non-well formed as only white space or comments and PIs are allowed before the first element.
can you help me in parsing xml with nested <?xml version="1.0" encoding="utf-8"?> tags. when i am trying to parse this xml, i m getting parsing error.
<?xml version="1.0" encoding="utf-8"?>
<soap>
<soapenvBody>
<serviceResponse>
<?xml version="1.0" encoding="UTF-8"?>
<data>
<respCode>0</respCode>
</data>
</serviceResponse>
</soapenvBody>
</soap>
I don't think this is really a Java problem. Having a second XML declaration within the XML body is just illegal, so I don't think you'll be able to get any XML parsers to parse that. If you have control over the XML (it looks like you're generating it to store a response) then you could try wrapping the inner-XML document with CDATA:
<?xml version="1.0" encoding="utf-8"?>
<soap>
<soapenvBody>
<serviceResponse>
<![CDATA[
<?xml version="1.0" encoding="UTF-8"?>
<data>
<respCode>0</respCode>
</data>
]]>
</serviceResponse>
</soapenvBody>
</soap>
EDIT:
I'm thinking that you most likely don't want the extra XML declaration inside that response at all. Do you have control over the code that creates the response? My guess is that the XML snippet <data>...</data> is created as a separate DOM object and then the string is spliced in the middle of the response. Writing out the entire XML document object results in the XML declaration being included, but if you just grab the document root node object (<data>) and write that out as a string then it probably won't include the extra XML declaration that's causing you all this trouble.
It occurred to me that a parser made for dealing with HTML might be able to do what you want. Since HTML tends to be a total mess compared to strict XML, HTML parsers are usually much more error-tolerant. A quick search turned up jsoup. I was able to pull the respCode from your sample XML above with roughly this code:
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
String data = "your xml goes here";
Document doc = Jsoup.parse(data);
String respCodeRaw = doc.select("respCode").first().text();
int respCode = Integer.valueOf(respCodeRaw);
(I actually tested the library in the Clojure repl, but the code above should work!)
A tag that starts with like <? is a processing instruction. <?xml...> is an XML declaration, and can only be present at the beginning of the xml content. It's not allowed in the XML body.
Why does your soap body contain this? Do you have the option of removing it?
i did not find any parser in java to parse such embedded xml as it is not a valid xml and i guess almost all parses validate the xml before parsing it. so i choose the option to preprocess the xml and selected the inner xml then using SAX parser i parsed the xml and retrieved the values from xml. Guys thanks for your replies.
