XSLT 无法删除属性值前后的换行符
XSLT unable to remove line break before and after attribute value
我正在尝试将 XSLT 3.0 和 Saxon 9.9 HE 的 XML 模式转换为 JSON。转型正在奏效。但是，当我输出一个属性的值时，它在名称前后都有一个换行符。 XSD 片段如下：
<group name="imapAttachmentDownloaderGroup">
<annotation>
<documentation>
Configuration block definitions for IMAP attachment downloader delegate. It contains all the configuration
block definitions that are required to configure the delegate successfully.
</documentation>
</annotation>
<sequence>
<element name="IMAPConnectorConfig">
<complexType>
<attribute name="imapHost" use="required" type="string">
<annotation>
<documentation>
This configuration block deals with the IMAP server name or IP address to where the
connection is to be made to download the attachments.
Example: "outlook.office365.com" or "40.100.137.66"
</documentation>
</annotation>
</attribute>
<attribute name="imapPort" use="required" type="int">
<annotation>
<documentation>
The port to use to connect to the server, defaults to 993.
Example: "993"
</documentation>
</annotation>
</attribute>
....
SXL如下：

}
</for-each>
}
<!-- <apply-templates select="attribute::name"/> -->

输出为：

我已经尝试了所有我能在帖子中找到的机制，将其分配给变量，normalize-space，normalize-space with string() with data()。似乎没有任何效果。任何帮助将不胜感激。

XSL（删除了所有注释和其他元素）：

=== 输出 ===

输入XSD保持不变。 Java代码如下：
String xsdFilePath="file:///D:/workspaces/mtplatform/PlatformManual_V1/PlatformManual/ProcessConfiguration/ProcessConfiguration.xsd";
String xslFilePath="file:///D:/workspaces/mtplatform/PlatformManual_V1/PlatformManual/ProcessConfiguration/ProcessConfiguration.xsl";
Processor processor=new Processor(false);
XdmNode node=processor.newDocumentBuilder().build(new File(new URI(xsdFilePath)));
XsltCompiler xsltCompiler=processor.newXsltCompiler();
//xsltCompiler.setParameter(new QName("delegateGroupName"), XdmValue.makeValue("imapAttachmentDownloaderGroup"));
StreamSource xsdSource=new StreamSource(new FileInputStream(new File(new URI(xsdFilePath))));
StreamSource xslSource=new StreamSource(new FileInputStream(new File(new URI(xslFilePath))));
XsltExecutable compiledXSL=xsltCompiler.compile(xslSource);
Xslt30Transformer xslTransformer=compiledXSL.load30();
HashMap<QName, XdmValue> parameterMap=new HashMap<>();
parameterMap.put(new QName("delegateGroupName"), XdmValue.makeValue("imapAttachmentDownloaderGroup"));
xslTransformer.setStylesheetParameters(parameterMap);
XdmValue output=xslTransformer.applyTemplates(node);
System.out.println(output.toString());
一般情况下，要控制文本输出，可以在表单
中使用xsl:text元素https://www.w3.org/TR/xslt-30/#xsl-text
<for-each select="child::xsi:sequence/child::xsi:element">
<text>,'</text>
<value-of select="attribute::name"/>
<text>':{</text>
此外，如果您使用 Xslt30Transformer 并想要文本形式的序列化结果，例如 JSON，其中格式由 XSLT 中的 xsl:output 定义，那么您应该使用 applyTemplates 的重载，允许您使用 Serializer 作为目标，即 http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#applyTemplates-net.sf.saxon.s9api.XdmValue-net.sf.saxon.s9api.Destination- with a Serializer created by the Xslt30Transformer (http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#newSerializer-java.io.OutputStream-)，因此在使用 System.out 测试结果的简单情况下，您会使用
Serializer serializer = xslTransformer.newSerializer(System.out);
xslTransformer.applyTemplates(node, serializer);
在您的 Java 案例中，您使用重载创建了一个 XdmValue，请注意它的文档 http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#applyTemplates-net.sf.saxon.s9api.XdmValue- 说它 returns
the raw result of applying templates to the supplied selection value,
without wrapping in a document node or serializing the result
正如您根据评论发现的那样，如果您有一个 XdmValue 并希望以受控方式对其进行序列化，您最好使用 [=16] 的 serializeXdmValue 方法=] 根据需要设置而不是简单地在 XdmValue.
