I am facing problem of extracting a data of 1*3072 into xml file. The last data can be saved is no.2500. Output truncated error occurred ever since there. Can anybody help? Here is my code:
docNode = com.mathworks.xml.XMLUtils.createDocument('LUT'); xmlwrite(docNode) entry_node = docNode.createElement('sigmaLUT');
a= signal(:,1); b= abs(a)';
entry_node.appendChild(docNode.createTextNode(sprintf('%i',b))); docNode.getDocumentElement.appendChild(entry_node); xmlwrite(docNode) xmlwrite('sigmaLUT.xml',docNode);

Hello,
You should split the data into multiple smaller XML elements or chunks rather than trying to dump all values into a single TextNode. Refer to the following example to write in chunks:
chunkSize = 500;
docNode = com.mathworks.xml.XMLUtils.createDocument('LUT');
rootNode = docNode.getDocumentElement;
entry_node = docNode.createElement('sigmaLUT');
for i = 1:chunkSize:length(b)
chunk = b(i:min(i+chunkSize-1, end));
chunkNode = docNode.createElement('chunk');
chunkNode.appendChild(docNode.createTextNode(sprintf('%i ', chunk)));
entry_node.appendChild(chunkNode);
end
rootNode.appendChild(entry_node);
xmlwrite('sigmaLUT.xml', docNode);
I hope this helps with your query!
