XSLT误解了document（）函数

我正在尝试合并2个xml文档，在第一个文档中获取一些属性值，然后将其注入另一个中。

我的第一个xml：Manual.xml有这样的形式：我有类似的5 000个任务：

           <task chapnbr="05"
                 sectnbr="11"
                 subjnbr="04"
                 pgblknbr="08"
                 breaknbr="001"
                 confnbr=""
                 confgtxt=""
                 func="200"
                 seq="001"
                 confltr=""
                 chg="u"
                 key="t051104200001"
                 revdate="20070615">
              <effect effrg="ALL">

我处理的第二个xml：Dictionary.xml：

<dictionary engine="CFM56" version="3" manual="ESM">
   <task oldkey="T050000870001"
         newkey="TKESM050000870001"
         chapnbr="05"
         sectnbr="00"
         subjnbr="00"
         func="870"
         seq="001">
      <title>GENERAL - INTRODUCTION</title>
   </task>
   <task oldkey="T051100200001"
         newkey="TKESM051100200001"
         chapnbr="05"
         sectnbr="11"
         subjnbr="00"
         func="200"
         seq="001">
      <title>LIFE LIMITS OF ENGINE ROTATING PARTS</title>
   </task>
   <task oldkey="T051101200001"
         newkey="TKESM051101200001"
         chapnbr="05"
         sectnbr="11"
         subjnbr="01"
         func="200"
         seq="001">
      <title>FAN ROTOR - LIFE LIMITS</title>
   </task>
   <task oldkey="T051102200001"
         newkey="TKESM051102200001"
         chapnbr="05"
         sectnbr="11"
         subjnbr="02"
         func="200"
         seq="001">
      <title>HIGH PRESSURE COMPRESSOR ROTOR - LIFE LIMITS</title>
</dictionary>

我需要获取属性的值＆＃34; seq＆＃34;如果属性＆＃34; oldkey＆＃34;在词典中并在手册中替换它。在词典中等于属性＆＃34; key＆＃34;在手册中。

要做到这一点，我已经写了这个XSLT：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions">

<xsl:output 
    encoding="UTF-8"
    method="xml" 
    indent="yes" 
    omit-xml-declaration="yes" 
    cdata-section-elements="comments"/>


<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="@seq[parent::task]">
    <xsl:variable name="oldkey" select="upper-case(../@key)"/>
    <xsl:attribute name="seq">
        <xsl:value-of select="document('./Dictionary.xml')/dictionary/task[@oldkey=$oldkey]/@seq"/>
    </xsl:attribute>
</xsl:template>  

</xsl:stylesheet>

但我得到的结果是＆＃34; seq＆＃34;的所有值。更改并替换为手册中的空白。这是输出的一个例子：

<task chapnbr="72"
                 sectnbr="00"
                 subjnbr="00"
                 pgblknbr="01"
                 breaknbr="011"
                 confnbr=""
                 confgtxt=""
                 func="810"
                 seq=""
                 confltr=""
                 chg="u"
                 key="t720000810011"
                 revdate="19981015">

我想我的问题来自于我使用document（）函数的方式，但我尝试过很多东西而且没有任何变化。结果总是一样的，我不会设法获得另一个值，除了属性中的空白＆＃34; seq＆＃34;我的输出文件手册。

我需要获得一个输出，其中属性＆＃34; seq＆＃34; value由3个整数组成，并从Dictionnary中读取。有点像：

<task chapnbr="72"
                 sectnbr="00"
                 subjnbr="00"
                 pgblknbr="01"
                 breaknbr="011"
                 confnbr=""
                 confgtxt=""
                 func="810"
                 seq="001"
                 confltr=""
                 chg="u"
                 key="t720000810011"
                 revdate="19981015">

更准确地了解我的输入/输出文件（Manual.xml）。完整文件的格式如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE EM [<!ENTITY g1105335-00 SYSTEM " file://D:/Indigo_AP/Load_CFM56-3/5-   Inputs/../Arts/1105335-00.tif" NDATA ccitt4>

我建议您运行以下样式表（针对任何格式良好的XML输入），看看你得到了什么：

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:variable name="dict" select="document('Dictionary.xml')" />
<xsl:variable name="key" select="'T050000870001'" />

<xsl:template match="/">
    <results>
        <dictionary-exists>
            <xsl:value-of select="boolean($dict)"/>
        </dictionary-exists>
        <entry-exists>
            <xsl:value-of select="boolean($dict/dictionary/task[@oldkey=$key])"/>
        </entry-exists>
        <value>
            <xsl:value-of select="$dict/dictionary/task[@oldkey=$key]/@seq"/>
        </value>
    </results>
</xsl:template>

</xsl:stylesheet>
