C#/XSLT : Linearizing XML partially working code

Question

输入 XML:

<foobar>
          <Comments>
            Reported By:   L &amp; A Q  TESTING, TESTED
            Date of TESTING:   Available
            TESTING  unavailable to resolve Test issue.
            Additional  Comments: Comments

            Had to go   into Testing System and change to the correct notification group. Per sup.
          </Comments>
</foobar>

XSLT 代码:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:strip-space elements="*"/>
    <xsl:output indent="no" omit-xml-declaration="yes"/>
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="text()">
        <xsl:value-of select="normalize-space()" />
    </xsl:template>
    <xsl:template match="text()[../*]"/>
</xsl:stylesheet>

预期输出:

<foobar><Comments>Reported By: L &amp; A Q TESTING, TESTED Date of TESTING: Available TESTING unavailable to resolve Test issue. Additional Comments: Comments Had to go into Testing System and change to the correct notification group. Per sup.</Comments></foobar>

我得到了什么:

<foobar>
  <Comments>Reported By: L &amp; A Q TESTING, TESTED Date of TESTING: Available TESTING unavailable to resolve Test issue. Additional Comments: Comments Had to go into Testing System and change to the correct notification group. Per sup.</Comments>
</foobar>

观察:

虽然 text() 节点中不必要的空格已被纠正..输出 XML 中仍然存在缩进。

理想情况下 strip-space 应该处理它.. 在它之上我添加了下面的代码

<xsl:template match="text()[../*]"/>

仍然没有运气!

的使用

XPathDocument xpathXmlOrig = new XPathDocument(string_xmlInput); 在我的 C# 代码中出错说 .. strip-space cannot be applied to document which has already been loaded!!所以我正在使用 XMLReader ..

添加 C# 代码以供引用..

        XslCompiledTransform xslTransform = new XslCompiledTransform();
        string xslinput = "<?xml version=\"1.0\"?><xsl:stylesheet version=\"1.0\" xmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\"><xsl:strip-space elements=\"*\"/><xsl:output indent=\"no\" omit-xml-declaration=\"yes\"/><xsl:template match=\"@*|node()\"><xsl:copy><xsl:apply-templates select=\"@*|node()\"/></xsl:copy></xsl:template><xsl:template match=\"text()[not(../*)]\"><xsl:value-of select=\"normalize-space()\" /></xsl:template><xsl:template match=\"text()[../*]\"/></xsl:stylesheet>";

        string strXmlOutput = string.Empty;
        StringWriter swXmlOutput = null;
        MemoryStream objMemoryStream = null;
        swXmlOutput = new StringWriter();
        objMemoryStream = new MemoryStream();

        UTC_Calc obj = new UTC_Calc();
        XsltArgumentList xslArg = new XsltArgumentList();
        ..........
        ........
        XmlReader reader = XmlReader.Create(string_xmlInput, settings);

        XsltSettings xslsettings = new XsltSettings(false, true);
        MemoryStream memStream = new MemoryStream();

        XmlReader rd = XmlReader.Create(new StringReader(xslinput));

        xslTransform.Load(rd);
        xslTransform.Transform(reader, xslArg, objMemoryStream);
        objMemoryStream.Position = 0;
        StreamReader objStreamReader = new StreamReader(objMemoryStream);
        strXmlOutput = objStreamReader.ReadToEnd();
        ..........
        ........

        XmlDocument outputxml = new XmlDocument();
        outputxml.LoadXml(strXmlOutput);
        outputxml.Save(outputfile.FileName);

您能否浏览一下您的代码，并查找您提供给写入流的任何 XmlWriterSettings？仔细检查它没有使用缩进输出选项。

如果没有类似的东西，也许显式传递声明不应发生格式化的 XmlWriterSettings 将解决此问题。

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = false;
/* .... */

var outWriter = XmlWriter.Create(outputstream, settings);
