How to convert Jsoup Document in a String without put spaces

问题

I have converted an XML document within a Document object Jsoup. Turns out, when I need to output to String format it generates this result below:

<?xml version="1.0" standalone="yes"?>
<NewDataSet xmlns="http://www.portalfiscal.inf.br/nfe"> 
 <nfeProc versao="2.00">
  <NFe> 
   <infNFe versao="2.00" id="NFe31140545453214002014550120002685744002685742"> 
 <cUF>
   31
 </cUF> 
 <cNF>
  00268574
 </cNF>
...

Scores generated this brings me a lot of problems, since he Colca whitespace within elements, and this causes me a big problem. Is there any way to generate an output that result without changing the values of the elements? I've tried changing the charset and use preetyprinter, but without success.

If commo generate the example below, without modifying the contents of the elements, there is a way to do this?

<?xml version="1.0" standalone="yes"?>
<NewDataSet xmlns="http://www.portalfiscal.inf.br/nfe"> 
 <nfeProc versao="2.00">
  <NFe> 
   <infNFe versao="2.00" id="NFe31140545453214002014550120002685744002685742"> 
 <cUF>31</cUF> 
 <cNF>00268574</cNF>
...

EDIT: input

String xml = "";

        while (reader.ready()) {
            xml += reader.readLine();
        }
        reader.close();
        doc = Jsoup.parse(xml, "", Parser.xmlParser());

output: I tried various ways, but always the same result as above...

 doc.toString();
 doc.outerHtml();
 doc.Html();

tried all methods that return a string, but always return the same.

回答1:

Generally, Jsoup will pretty-print the read in xml. You can turn off that behavior with

doc.outputSettings().prettyPrint(false);

However, then JSoup will probably use the same formatting as the input. In your case that contains maybe also new line characters around the <cUF> tags, so you are out of luck there.

I am not sure how your original xml is formatted really. But maybe this can be of help:

while (reader.ready()) {
    xml += reader.readLine().replaceAll("\n","");
}
reader.close();
doc = Jsoup.parse(xml, "", Parser.xmlParser());
doc.outputSettings().prettyPrint(false).indentAmount(0);

System.out.print(doc.html());

Explanation: I remove all NEW LINE characters before the parsing. Then I set the pretty print to off.
