我有以下測試代碼，試圖將CVS文件轉換爲XML。我的問題是，有時它會運行，它失敗，出現以下錯誤其他時間：SAXON XSLT錯誤
The specified node cannot be inserted as the valid child of this node, because the specified node is the wrong type.
下面是代碼：
XsltCompiler compiler = null;
try
{
Processor processor = new Processor();
compiler = processor.NewXsltCompiler();
var sr = new StreamReader(@"c:\files\drop\csv-to-xml_v2.xslt");
var xslt = sr.ReadToEnd();
sr.Close();
StringReader reader = new StringReader(xslt);
XsltExecutable exec = compiler.Compile(reader);
XsltTransformer transformer = exec.Load();
transformer.InitialTemplate = new QName("", "main");
var XmlResult = new DomDestination();
transformer.Run(XmlResult);
reader.Close();
}
catch (Exception ex)
{
var errMsg = ex.Message;
var errList = compiler != null ? compiler.ErrorList : null;
}
的XSLT是：
<?xml version="1.0"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:fn="fn"
exclude-result-prefixes="xs fn">
<xsl:output indent="yes" encoding="US-ASCII"/>
<xsl:param name="pathToCSV" select="'file:///C:/Files/Drop/inputcsv1.csv'"/>
<xsl:function name="fn:getTokens" as="xs:string+">
<xsl:param name="str" as="xs:string"/>
<xsl:analyze-string select="concat($str, ',')" regex='(("[^"]*")+|[^,]*),'>
<xsl:matching-substring>
<xsl:sequence select='replace(regex-group(1), "^""|""$|("")""", "$1")'/>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:function>
<xsl:template match="/" name="main">
<xsl:choose>
<xsl:when test="unparsed-text-available($pathToCSV)">
<xsl:variable name="csv" select="unparsed-text($pathToCSV)"/>
<xsl:variable name="lines" select="tokenize($csv, '
')" as="xs:string+"/>
<xsl:variable name="elemNames" select="fn:getTokens($lines[1])" as="xs:string+"/>
<root>
<xsl:for-each select="$lines[position() > 0]">
<row>
<xsl:variable name="lineItems" select="fn:getTokens(.)" as="xs:string+"/>
<xsl:for-each select="$elemNames">
<xsl:variable name="pos" select="position()"/>
<column>
<xsl:value-of select="$lineItems[$pos]"/>
</column>
</xsl:for-each>
</row>
</xsl:for-each>
</root>
</xsl:when>
<xsl:otherwise>
<xsl:text>Cannot locate : </xsl:text><xsl:value-of select="$pathToCSV"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
任何人都可以看到爲什麼有時它的工作原理，然後沒有理由在「transformer.Run（XmlResult）」行失敗？我正在使用C＃4，Visual Studio 2010和Saxon 9 HE。
