javascript - 如何删除XML文件中的LF以接收一行xml文件？

Question

我有一个文件 theme.xml 不包含“LF”，请参阅 https://en.wikipedia.org/wiki/Newline 。但在转换为 js 并返回 xml 后，我的结果包含“LF”换行符。这是一个问题，因为adobe acrobat 8​​标准要求xml文件在一行中作为标题模板文件。听一个例子:

<?xml version = "1.0" encoding = "UTF-8" ?><HeaderFooterSettings version = "8.0"><Font name="Arial" size="11.0"/><Color b="0.0" r="0.0" g="0.0"/><Margin top="34.0159" left="72.0002" right="72.0002" bottom="36.0001"/><Appearance shrink="1" fixedprint="0"/><PageRange end="-1" start="-1" even="1" odd="1"/><Page offset = "0"><PageIndex format="1"/></Page><Date><Month format="1"/>/<Day format="1"/><Year format="0"/></Date><Header><Left>hello</Left><Center></Center><Right>world</Right></Header><Footer><Left></Left><Center></Center><Right></Right></Footer></HeaderFooterSettings>






var fs = require('fs');
var path = require('path');
var xml2js = require('xml2js');

xmlFileToJs('theme.xml', function (err, obj) {
    if (err) throw (err);
    jsToXmlFile('theme2.xml', obj, function (err) {
        if (err) console.log(err);
    })
});


function xmlFileToJs(filename, cb) {
    var filepath = path.normalize(path.join(__dirname, filename));
    fs.readFile(filepath, 'utf8', function (err, xmlStr) {
        if (err) throw (err);
        xml2js.parseString(xmlStr, {}, cb);
    });    
}

function jsToXmlFile(filename, obj, cb) {
    var filepath = path.normalize(path.join(__dirname, filename));
    var builder = new xml2js.Builder();
    var xml = builder.buildObject(obj);
    fs.writeFile(filepath, xml, cb);
}

不幸的是，linebrakers“LF”的结果

 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<HeaderFooterSettings version="8.0">
  <Font name="Arial" size="11.0"/>
  <Color b="0.0" r="0.0" g="0.0"/>
  <Margin top="34.0159" left="72.0002" right="72.0002" bottom="36.0001"/>
  <Appearance shrink="1" fixedprint="0"/>
  <PageRange end="-1" start="-1" even="1" odd="1"/>
  <Page offset="0">
    <PageIndex format="1"/>
  </Page>
  <Date>
    /
    <Month format="1"/>
    <Day format="1"/>
    <Year format="0"/>
  </Date>
  <Header>
    <Left>hello</Left>
    <Center/>
    <Right>world</Right>
  </Header>
  <Footer>
    <Left/>
    <Center/>
    <Right/>
  </Footer>
</HeaderFooterSettings>

我尝试了很多。即时，但无法通过此命令找到解决方案:

const stringify = require('xml-stringify');
var xmlc = require('xml');
const trimNewlines = require('trim-newlines');
xmlc(trimNewlines(JSON.stringify(obj)));

我也尝试过这个:

var builder = new xml2js.Builder({'trim' : true, 'normalize' : true});

好吧，没有机会。

我期待其他想法。

现在您可以使用

const builder = new xml2js.Builder({ renderOpts: { pretty: false } });
