Invalid XML characters

When parsing String to XML, I get org.xml.sax.SAXParseException, with the message: An invalid XML character (Unicode: 0xb) was found in the element content of the document.
What are invalid XML characters? How do I avoid this Exception?
Thanks.

Here is what the XML Recommendation says are valid characters for XML:Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]Invalid characters are anything else. And it should be obvious that to avoid that exception you should not attempt to parse files that contain any invalid characters.

Convert invalid xml characters to HTML-Entity

Hi,
How can i convert invalid XML characters like �,�,�, . . . to the HTML- Entity &auml &uuml &ouml ?
Is there any Method or class who can handle an input string and transform the invalid characters?
Or is there another way to mask this characters so that an XML parser do not throw an error when parsing the document.
Best regards,
Michael

Ok sorry, I'll give you more details what i want to do and where i have the problems.
I have the following xml string:
<font family="Times New Roman" size="14" color="#333333">This is a sample Text</font>
The xml-string can contain any characters because the content is from a text pane where the user can type in any characters.
I use the DOM parser to parse this input string to get the attributes and the text content.
And thats my problem, how can i make sure that this string wont throw any exceptions when i parse it with DOM?
Parsing the string with the follwing code:
public XMLElement parse(String sourceString)
        //create a new xml element
        XMLElement xmlElement = new XMLElement();
        //create a new document
        DocumentBuilder builder = build();
        //now parse the string into the document
        InputStream is = new ByteArrayInputStream(sourceString.getBytes());
        Document document = null;
        try
            document = builder.parse(is);
        catch (SAXException e)
            System.out.println("SAXError while parsing the document");
            e.getMessage();
            //no valid document
            return null;
        catch (IOException e)
            System.out.println("IO Error while parsing the document");
            e.getMessage();
            //no valid document
            return null;
        //get the element
        org.w3c.dom.Element element = document.getDocumentElement();
        if (element != null)
            xmlElement.setNodeName(element.getNodeName());
            xmlElement.setNodeValue(element.getTextContent());
            //attributes defined?
            int length = element.getAttributes().getLength();
            //get the attributes, if defined
            for (int i = 0; i < length; i++)
                xmlElement.addAttribute(
                        element.getAttributes().item(i).getNodeName(),
                        element.getAttributes().item(i).getTextContent());
        return xmlElement;
    } XMLElement is my own class.
The builder:
private DocumentBuilder build()
        DocumentBuilder docBuilder = null;
        try
            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            docBuilder = factory.newDocumentBuilder();
        catch(ParserConfigurationException pce)
            System.out.println("Error while creating an DocumentBuilder");
            pce.getMessage();
        //return the document builder
        return docBuilder;

Javax.xml.parsers.DocumentBuilder to skip invalid XML characters?

Hi,
I convert XML files into flat files. In doing so I call the API DocumentBuilder.parse(File f). If the XML file f contains an invalid XML character, the API throws a SAXException.
My question is: while I know that certain invalid XML chars are not part of the data and therefore can be safely ignored in the conversion, is there a way to tell the API to skip those chars?

Nope. Compliant XML parsers are required to parse the XML as it is and not to "repair" it in any way. Your best option is not to have badly-formed XML in the first place, so if you are the one generating the XML, you should fix that process. But if you have bozo customers generating it, and you can't make them do it right, then pre-process the XML to drop the bad characters.

Replace invalid XML characters using SQL query

Hi,
I am populating a dataset in .net with output from sql 2005 database. One of the columns in the table is a 'varchar(max)' type. This dataset is then converted to XML using WriteXml and written to a .xml document. But due to the presence of invalid characters, this process errors out.
Is there any way using which these invalid characters can be replaced at the database level itself when querying on the table?
The error that is produced is as follows:
'', hexadecimal value 0x1C, is an invalid character. Line 32201, position 924.
Thanks,
Nisha

I see,
So we have a certain character that the XML processor does not like. What do you want to do with this character? Even if you manage to make an XML file wth this some how, you will get the same problem when another application tries to read it.
Probably you should replace those characters before converting the values to XML.
Another option is to put the values to the CDATA. This will be tough because the query might be little tricky. Here is an example that might help you.
Code Snippet
CREATE TABLE CDataTest (SomeValue NVARCHAR(50))
INSERT INTO CDataTest (SomeValue) SELECT 'Some Value ' + CHAR(25) + 'Some OtherValue'
SELECT * FROM CDataTest FOR XML AUTO, TYPE
error!!!
FOR XML could not serialize the data for node 'SomeValue' because it contains
a character (0x0019) which is not allowed in XML. To retrieve this data using
FOR XML, convert it to binary, varbinary or image data type and use the
BINARY BASE64 directive.
-- option using CDATA
SELECT
1
AS Tag,
NULL AS Parent,
(SELECT
SomeValue AS 'data()'
FROM CDataTest
FOR XML PATH('')) AS 'SomeValue!1!SomeValue!cdata'
FROM CDataTest
FOR XML EXPLICIT, TYPE
<SomeValue>
<SomeValue><![CDATA[Some Value Some OtherValue]]></SomeValue>
</SomeValue>

Invalid XML character in web service answer of MS Exchange

Hello Forum!
We have to look up contacts in the global address list of a Microsoft Exchange server.
The current solution uses the web services that have been introduced in version 2007 of MS Exchange.
Unfortunately some records returned by the MS Server cause a javax.xml.stream.XMLStreamException. The Exception
tells us that a parser error occurred. The Exception says:
Message: Character reference "&#x7" is an invalid XML character.
The Java classes used for accessing the Exchange web services are generated using the jaxws plugin and the application
is running on the Glassfish application server v2 ur1.
The only solution we can think of right now is to access the XML stream returned by the Exchange server before it is handed over
to the parser in order to replace the invalid characters.
Can anyone point me to some documentation or give me an example of how to intercept the XML parsing process used by the jaxws
component?
Any other ideas for a solution are of course also appreciated.
Thanks for your help in advance,
Henning Malzahn

In addition to that MS is not very responsive when it comes to Java questions.Yes, but "Your software is producing malformed XML" is not a Java question.
I can imagine that filtering the stream isn't very easy - are you able to provide some links to additional
information that can help us getting started in that direction?A subclass of FilterInputStream whose read() method calls the superclass's read() method a second time when the input is between 0 and 19, or whatever are the invalid XML characters?

How to filter invalid XML character

I need to form an XML document in the program. There are some invalid characters like 0x8.
How can I remove the invalid XML characters?
Is there any existing tool (function) I can use to check whether the character is an invalid or valid XML character?
Thank you.
waterii

you can set dataProvider filterFunction to filter the data

Inavlid XML characters & Cryptography

HI,
I am using JSR 172 to communicate between my mobile and a remote server. What actually i am doing is that i am encrypting my data & then sending it over the internet using a GPRS connection in the form of XML But due to encryption, the invalid XML characters also appear in the XML document. Can any body tell how can i remove the illegal XML characters from XML document. I would be deeply thankful to the person guiding me in this regard...
Wasif Ehsan.

sounds like you need to employ an encryption algorithm that produces encrypted data that adheres xml's required charset:
http://www.w3.org/TR/2000/REC-xml-20001006#NT-Char
any 'illegal' characters put into your xml file will most likely throw an exception while being marshalled via your webservices calls.

Fix Invalid XML character (Unicode: 0x1c) before xml data parsing

How to fix the error :- "An invalid XML character (Unicode: 0x1c) was found in the element content of the document."
This error message is generated before parsing of xml data.
So how to filter the unwanted characters like 0x1c during XML file generation?

ASCII has nothing to do with it. XML is a text format and so an XML file may only include text characters. 0x7 isn't a text character, it's a control character, and it isn't allowed to occur in an XML file.
As for how to identify which character is causing the problem, the error message tells you that.

Invalid XML character in castor XML

I am using castor API for converting an object into XML. When I marshal the object, following exception occur:
java.io.IOException: The character '' is an invalid XML character
     at org.apache.xml.serialize.BaseMarkupSerializer.characters(Unknown Source)
     at org.exolab.castor.xml.Marshaller.marshal(Unknown Source)
     at org.exolab.castor.xml.Marshaller.marshal(Unknown Source)
     at org.exolab.castor.xml.Marshaller.marshal(Unknown Source)
Following is the code snippet which I am using:
StringWriter writer = new StringWriter(500);
Marshaller marshal = new Marshaller(writer);
marshal.setEncoding("windows-1251"); //I have tried all these encodings as well: UTF-8, UTF-7, ASCII, ISO-8859-1, ISO-8859-5, windows-1251
//marshal.marshal(token, writer);     // This is commented, since the encoding is not applied if I use this method, next statement works fine
marshal.marshal(token);Here, token is the object which I am trying to marshal. I have tried different encodings, but the problem is not resolved. Could anyone help?
Castor reference:
[http://www.castor.org/xml-framework.html ]

Do you want this encoding to be reversible? For example, that character \u001b which is in the string. You have to represent it by something different in your XML. If you want to get the same thing back when you convert your XML back into Java, then you can't just translate that character into an existing character, because then you have lost information. You have to translate it into some special series of codes. And then when you convert the XML back, you have to recognize that special series of codes and convert that into the \u001b character.
So yeah, you could write your own custom encoding which did that. I'm not aware of any existing software that does that; it wouldn't be very useful, because it would result in XML documents which used non-standard encodings and hence couldn't be sent to anybody else.

Handle invalid xml character while serializing

I have requirement where I need to serialize a document which contains a string like "ﾝￊￒ%ﾝￋ &". While serializing it throws the following exception
java.io.IOException: The character ' ' is an invalid XML character
Is there a way we can serialize this String as is with any workaround.
StringWriter stringOut = new StringWriter();
DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
Document doc = docBuilder.newDocument();
Element rootElement = doc.createElement("company");
doc.appendChild(rootElement);
String xml = "ﾝￊￒ%ﾝￋ &";
//String xml = "ﾝￊￒ%ﾝￋ &";
Element junk = doc.createElement("replyToQ");
junk.appendChild(doc.createCDATASection(xml));
//junk.appendChild(doc.createTextNode(stripNonValidXMLCharacters(xml)));
rootElement.appendChild(junk);
//org.w3c.dom.Document doc = this.toDOM();
//Serialize DOM
OutputFormat format = new OutputFormat(doc,"UTF-8",true);
format.setIndenting(false);
format.setLineSeparator("");
format.setPreserveSpace(true);
format.setOmitXMLDeclaration(false);
XMLSerializer serial = new XMLSerializer( stringOut, format );
// As a DOM Serializer
serial.asDOMSerializer();
serial.serialize( doc.getDocumentElement() );

As a guess because you are treating CDATA as meaning the same as 'binary' which it isn't. The characters in CDATA still must be valid XML characters.
If you want binary data then base64 encode it and put that in the document - and you won't need CDATA at all then, it will just be regular element text.

Getting invalid xml character while marshalling

Hi
I have a text which contains all characters including some special chars.I am replacing the html codes for &,>,<,\," characters. I am building the xml file and trying to marshall it. But i am getting "The character '' is an invalid XML character". I am using castor-0.9.6.jar. Can any one tell me how can i handle special chars like � is easy way rather than repacing each and every character.
Please let me know why i am getting the above error (is the special char end of file char. actually i am reating from string not from file).
Thanks & Regards,
Prasanth

Mapping error: Character reference "&# 00" is an invalid XML character

Hi All,
Iam performing the RFC(R/3) -> PI(7.1) -> SOAP (third party software) ; Synchronous scenario.
The messages are reaching the PI server , but the a mapping errors is occurring due to dummy characters ""& #00" been sent to the XI system.
Is this due to the R/3 sending the invalid characters or these been generated in PI system. Would you suggest any notes,patches to resolve the issue?

Hi,
If you go through this link last page and last para, which says..

Invalid XML character. (Unicode: 0x7)

Hi There,

Any idea how i cld overcome this problem or identify which/what character is causing this problem? Am using a xmk4j 2.x parser.
Tks is advance.

Invalid xml character(0x0)

Hi All,
I am generating an xml file using JAXB using ISO-8859-1 encoding.
While parsing that xml file using XmlReader , I am getting exception as "UnmarshallerException : invalid xml character(0x0) found in xml ".
Can I put some filter before creating xml file using JAXB so that it wont allow an invalid character to be written into xml file ?
Please provide some code ,

Hi Xavi,
" suppose we have to do it before to take the file, or another way could be to take the file without content conversion, and with a java mapping delete the nulls and create the message we send to R/3.
What do you think about this?"
Ans)
Yes that's correct. You can follow this blog http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/4018
where without FCC the mapping code directly creates the target XML. you can add code to replace all null characters as example shown below
String line = bin.readLine();
String s="";
for(int i=0;i<line.length();++i)
if(line.charAt(i)!=)0X00)
s=s+line.charAt(i);
line=s;
Any source interface is fine in interface mapping and no need to use FCC. Rest all setrtings will be normal as per the blog.
