我目前正在java中将xml写入xml doc,但格式不正确,格式如下:
<book id="bk102">
<author>Ralls, Kim</author>
<title>Midnight Rain</title>
<genre>Fantasy</genre>
<price>5.95</price>
<publish_date>2000-12-16</publish_date>
<description>A former architect battles corporate zombies,
an evil sorceress, and her own childhood to become queen
of the world.</description>
</book>
而不是像这样,我可以做些什么来正确地将其与文档的其余部分对齐?
<book id="bk102">
<author>Ralls, Kim</author>
<title>Midnight Rain</title>
<genre>Fantasy</genre>
<price>5.95</price>
<publish_date>2000-12-16</publish_date>
<description>A former architect battles corporate zombies,
an evil sorceress, and her own childhood to become queen
of the world.</description>
</book>
我得到了关于可能重复的回复,可能是这种情况,但在我的情况下,它在这里不起作用是我的代码:
private void writeFile(File file) {
Transformer transformer = TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
StreamResult resultStream = new StreamResult(new StringWriter());
DOMSource source = new DOMSource(getDocument());
transformer.transform(source, resultStream);
BufferedWriter out = new BufferedWriter(new FileWriter(file));
out.write(resultStream.getWriter().toString().trim());
out.close();
}

你试过了吗?
StreamSource stylesource = new StreamSource(getClass().getResourceAsStream("proper-indenting.xsl"));
Transformer transformer = TransformerFactory.newInstance().newTransformer(stylesource);
xsl source是:
<!DOCTYPE stylesheet [
<!ENTITY cr "<xsl:text>
</xsl:text>">
]>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xslt"
version="1.0">
<xsl:output method="xml" indent="yes" xalan:indent-amount="3"/>
<!-- copy out the xml -->
<xsl:template match="* | @*">
<xsl:copy><xsl:copy-of select="@*"/><xsl:apply-templates/></xsl:copy>
</xsl:template>
</xsl:stylesheet>

将OutputKeys.INDENT设置为“yes”应该是所需的全部内容。遗憾的是,随着jre一起提供的xalan版本仅在要求格式化输出时在元素之后插入换行符。您可以尝试更新版本的xalan或使用saxon,它肯定支持格式良好的输出。

System.out.print("YOUR SPACES");
