我正在尝试将带有Saxon 9.9 HE的XSLT 3.0的XML模式转换为JSON。转换正在进行中。但是，当我输出属性的值时，该属性的名称前后都有换行符。 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：
<?xml version="1.0" encoding="UTF-8"?>
<stylesheet version="3.0"
xmlns="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema"

xsi:schemaLocation="http://www.w3.org/1999/XSL/Transform
https://www.w3.org/2007/schema-for-xslt20.xsd">

<strip-space elements="*" />
<!-- <template match="text()|@*"/> -->
<param name="delegateGroupName" required="yes"/>
<template match="/child::xsi:schema/child::xsi:group[attribute::name=$delegateGroupName]">
<variable name="xx" select="attribute::name"/>
{'groupName':'<value-of select="normalize-space($xx)"/>'
<for-each select="child::xsi:sequence/child::xsi:element">
,'<value-of select="attribute::name"/>':{
<for-each select="child::xsi:complexType/child::xsi:attribute">
<choose>
<when test="position()=last()">'name':'<value-of select="attribute::name"/>'</when>
<otherwise>'name':'<value-of select="attribute::name"/>',</otherwise>
</choose>
</for-each>
<for-each select="child::xsi:complexType/child::xsi:attributeGroup">
<value-of select="attribute::ref"/>
</for-each>
}
</for-each>
}
<!-- <apply-templates select="attribute::name"/> -->
</template>
输出为：
{'groupName':'
imapAttachmentDownloaderGroup
'
, '
IMAPConnectorConfig
':{
'name':'
imapHost
',
'name':'
imapPort
',
'name':'
sslEnabled
',
'name':'
startTLSEnabled
',
'name':'
imapUser
',
'name':'
imapPassword
',
'name':'
credentialId
我尝试了所有可以在帖子中找到的机制，将其分配给具有string（）和data（）的变量，normalize-space，normalize-space。似乎没有任何作用。任何帮助将由衷的感谢。
===包括完整的示例===
XSL（已删除所有注释和其他元素）：
<?xml version="1.0" encoding="UTF-8"?>
<stylesheet version="3.0"

<template match="/child::xsi:schema/child::xsi:group[attribute::name=$delegateGroupName]">

===输出===
{"groupName":"

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());
答案 0 :(得分：1)
通常，要控制文本输出，可以使用以下形式的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并希望以文本形式（如JSON）的序列化结果，其格式由XSLT中的xsl:output定义，则应使用重载applyTemplates允许您将Serializer用作目的地，即http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#applyTemplates-net.sf.saxon.s9api.XdmValue-net.sf.saxon.s9api.Destination-与Serializer（http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#newSerializer-java.io.OutputStream-）创建的Xslt30Transformer，因此使用System.out测试结果的简单案例
Serializer serializer = xslTransformer.newSerializer(System.out);
xslTransformer.applyTemplates(node, serializer);
在您的Java情况下，您已使用重载来创建XdmValue，请注意其文档http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#applyTemplates-net.sf.saxon.s9api.XdmValue-说它返回了
将模板应用于所提供的选择值的原始结果， 无需包装在文档节点中或序列化结果
根据评论发现，如果您有XdmValue并希望以受控方式对其进行序列化，则最好使用serializeXdmValue的{{1}}方法进行设置，而不是简单地在Serializer上调用toString。
