If you use lxml, you can specify a parser that keeps CDATA:

import lxml.etree

file_name = r 'inputData.xml'
parser = lxml.etree.XMLParser(strip_cdata = False)
tree = lxml.etree.parse(file_name, parser)
root = tree.getroot()
c = lxml.etree.Element("c")
c.text = "3"
root.insert(1, c)
tree.write("outputData.xml")

I am trying to convert existing Xml file to anycodings_python another xml file with adding few nodes. But anycodings_python when i parse my original xml file and write anycodings_python it to the another xml file, it removes all anycodings_python the CDATA from the output xml. How can i anycodings_python avoid it ?,Can't scroll to top of flex item that is overflowing container,Python Multiprocess Pool. How to exit the script when one of the worker process determines no more work needs to be done?,Django , password dont match error message not displaying. Customised UserAuth app

Here is my code:

tree = ET.parse(r 'inputData.xml')
root = tree.getroot()
c = ET.Element("c")
c.text = "3"
root.insert(1, c)
tree.write("outputData.xml")

This is my input XML

If you use lxml, you can specify a anycodings_cdata parser that keeps CDATA:

import lxml.etree

file_name = r 'inputData.xml'
parser = lxml.etree.XMLParser(strip_cdata = False)
tree = lxml.etree.parse(file_name, parser)
root = tree.getroot()
c = lxml.etree.Element("c")
c.text = "3"
root.insert(1, c)
tree.write("outputData.xml")

A CDATA section is used to mark a section of an XML document, so that the XML parser interprets it only as character data, and not as markup. It comes handy when one XML data need to be embedded within another XML document.,To avoid stripping or ignoring the content of element1 in the above scenarios, you can wrap the child element, element1 in a CDATA section, or by using character entities.,The CDATA section is treated as a block of character data by the parser, allowing inclusion of any character in the data stream. CDATA section starts with the special sequence <![CDATA[ and ends with the ]]> sequence. After the TXSeries XML parser identifies the CDATA sections, it strips out the delimiter <![CDATA[ and ]]> and treats the text contents as raw text. Anything between those delimiter will pass through the XML parser untouched.,Parser will ignore all the content followed by the first bracket < in element1. This scenario will lead to the following exception, as element1 content will be empty,

1._
<element>text content</element>
&amp;
<element><text>
      <content>
</element>
1._
<element>&amp;lttext&amp;gt;<content< /element>
<element>&amp;lttext&amp;gt;<content</element>
<element>&amp;lttext<content< /element>
<element>
   <![CDATA[<text><content>]]>
</element>
1._
<element1> text1 <element2> text2 </element2>
</element1>
<element1> text1 <element2> text2 </element2> </element1>
<element1> text1 <element2> text2 </element2> text3 </element1>
element1
<element1>
   <element2> text2 </element2>
</element1>
<element1> <element2> text2 </element2> </element1>
<element1>
   <element2> text2 </element2> text3
</element1>

But text inside a CDATA section will be ignored by the parser.,Parsed Character Data (PCDATA) is a term used about text data that will be parsed by the XML parser. ,All text in an XML document will be parsed by the parser.,Everything inside a CDATA section is ignored by the parser.

<message>This text is also parsed</message>
<name>
   <first>Bill</first>
   <last>Gates</last>
</name>
<name>
   <first>Bill</first>
   <last>Gates</last>
</name>
<script>
<![CDATA[
function matchwo(a,b)
{
if (a < b && a < 0) then
   {
   return 1;
   }
else
   {
   return 0;
   }
}

The data is not parsed because it is in a CDATA section when you select the value of PAYLOAD. ,Here are some helpful hints for using the XML Parser for Java. This section contains these topics: ,When using the DOM interface, use more attributes than elements in your XML to reduce the pipe size. ,Finally, escaping invalid characters is a workaround to give people a way to serialize names so that they can reload them somewhere else.

This mechanism provides "universal" namespace element types and attribute names. Such tags are qualified by uniform resource identifiers (URIs), such as: 

<oracle:EMP xmlns:oracle="http://www.oracle.com/xml" />

If your application has to parse several XML documents with the same DTD, after you parse the first XML document, you can get the DTD from parser and set it back: 

dtd = parser.getDoctype();
parser.setDoctype(dtd);

Set the DOMParser.USE_DTD_ONLY_FOR_VALIDATION attribute, if the cached DTD Object is used only for validation by: 

parser.setAttribute(DOMParser.USE_DTD_ONLY_FOR_VALIDATION, Boolean.TRUE);

The method to set the DTD is setDoctype(). Here is an example: 

// Test using InputSource 
parser = new DOMParser();
parser.setErrorStream(System.out);
parser.showWarnings(true);

FileReader r = new FileReader(args[0]);
InputSource inSource = new InputSource(r);
inSource.setSystemId(createURL(args[0]).toString());
parser.parseDTD(inSource, args[1]);
dtd = (DTD) parser.getDoctype();

r = new FileReader(args[2]);
inSource = new InputSource(r);
inSource.setSystemId(createURL(args[2]).toString());
// ********************
parser.setDoctype(dtd);
// ********************
parser.setValidationMode(DTD_VALIDATION);
parser.parse(inSource);
 

doc = (XMLDocument) parser.getDocument();
doc.print(new PrintWriter(System.out));

Load the DTD as an InputStream: 

InputStream is = YourClass.class.getResourceAsStream("/foo/bar/your.dtd");

Parse the DTD: 

DOMParser d = new DOMParser();
d.parseDTD(is, "rootelementname");
d.setDoctype(d.getDoctype());

Parse your document: 

d.parse("yourdoc");

The parseDTD() method enables you to parse a DTD file separately and get a DTD object. Here is some sample code to do this: 

DOMParser domparser = new DOMParser();
domparser.setValidationMode(DTD_VALIDATION);
/* parse the DTD file */
domparser.parseDTD(new FileReader(dtdfile));
DTD dtd = domparser.getDoctype();
