nodejs elementtree npm etree.write() 漂亮的打印

Question

我在为 nodejs 使用 etree npm 时遇到了运行问题。我在我的应用程序中广泛使用了 elementtree npm，所以我无法承担更改 npm 的费用。我正在使用以下代码编写 XML。

var et = require('elementtree');
tailorData = fs.readFileSync(XML_FILE).toString();
etree = et.parse(tailorData);
// Do some changes in xml
var resultXml = etree.write(); // DOES NOT DO PRETTY PRINTING
fs.writeFileSync(tailoredXML, resultXml);

etree.write() 把整个 XML 搞砸了，我后来的处理也停止了。它不会在标签后放置尾行。这就是 XML 现在的样子。

<?xml version='1.0' encoding='utf-8'?><Tailoring id="1234"><status>incomplete</status><Profile id="CIS_LEVEL_1"><title>CIS_LEVEL_1 Security Profile</title><select idref="file_group_owner_grub2_cfg" selected="true" /><select idref="file_user_owner_grub2_cfg" selected="true" /><select idref="file_permissions_grub2_cfg" selected="true" /></Profile></Tailoring>

以下是我的预期：

<?xml version='1.0' encoding='utf-8'?>
<Tailoring id="1234">
<status>incomplete</status>
<Profile id="CIS_LEVEL_1">
<title>CIS_LEVEL_1 Security Profile</title>
<select idref="file_group_owner_grub2_cfg" selected="true" />
<select idref="file_user_owner_grub2_cfg" selected="true" />
<select idref="file_permissions_grub2_cfg" selected="true" />
</Profile>
</Tailoring>

他们有什么方法可以在 nodejs 中实现上述结果。

Answer 1

找到方法了。使用非常轻量级的 npm "pretty-data" 来实现这一点。

var pd = require('pretty-data').pd;

var et = require('elementtree');
tailorData = fs.readFileSync(XML_FILE).toString();
etree = et.parse(tailorData);
// Do some changes in xml
var resultXml = etree.write();
resultXml = pd.xml(resultXml); // THIS WILL DO THE PRETTY PRINTING.
fs.writeFileSync(tailoredXML, resultXml);
