c# /XSLT:线性化XML部分工作代码

本文关键字：工作 代码 XML 线性化 XSLT | 更新日期: 2023-09-27 18:01:36

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>

我得到的是:

<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:

虽然从text()节点不必要的空白已被纠正…输出XML中仍然有缩进。

理想情况下，strip-space应该照顾它。在上面我添加了下面的代码

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

还是没有运气!!

的用法

XPathDocument xpathXmlOrig = new XPathDocument(string_xmlInput);在我的c#代码错误说…条带空间不能应用于已经加载的文档!!所以我使用XMLReader .

添加c#代码供参考…

        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);

你可以浏览你的代码，并寻找任何XmlWriterSettings，你给你的写流?再次检查它是否没有使用缩进输出选项。

如果那里没有这样的东西，也许显式地传递XmlWriterSettings声明不应该发生格式化将解决这个问题。

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = false;
/* .... */
var outWriter = XmlWriter.Create(outputstream, settings);
http://msdn.microsoft.com/en-us/library/system.xml.xmlwritersettings.aspx

Used 

TextWriter writer = File.CreateText(outputfile.FileName);
writer.Write(strXmlOutput);
writer.Close();

代替现有代码:

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

我想我也能理解两者的区别。

XmlDocument (outputxml.LoadXml, outputxml.Save)，默认强制缩进。虽然strXmlOutput没有任何缩进…

我得到了这个修复参考杰克Heidt的答案。把它标记为社区维基，因为它不是我自己的答案。此外，这个答案可以编辑更多有用的信息(如果需要)
