如何在不带空格的字符串中转换Jsoup文档 [英] How to convert Jsoup Document in a String without put spaces

问题描述

我已经在Document对象Jsoup中转换了XML文档.原来，当我需要输出为String格式时，它会在下面生成此结果:

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>
...

生成的分数给我带来了很多问题，因为他在元素内使用了Colca空格，这给我带来了一个大问题.有什么方法可以在不更改元素值的情况下生成结果输出?我尝试过更改字符集并使用preetyprinter，但没有成功.

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.

如果commo在不修改元素内容的情况下生成以下示例，有没有办法做到这一点?

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>
...

输入

String xml = "";

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

输出:我尝试了各种方法，但结果始终与上述相同...

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

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

尝试了所有返回字符串的方法，但始终返回相同的方法.

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

推荐答案

通常，Jsoup将漂亮打印 xml读取的内容.您可以使用

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

doc.outputSettings().prettyPrint(false);

但是，那么JSoup可能会使用与输入相同的格式.就您而言，在< cUF> 标记周围可能还包含换行符，因此您不走运.

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.

我不确定您的原始xml的格式是否正确.但这可能会有所帮助:

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());

说明:我在解析之前删除了所有NEW LINE字符.然后我将漂亮的打印设置为关闭.

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