将FLAT文件修复为XML

Question

在XSLT 2.0上需要一些帮助。

以下是使用未解析文本和使用文档参考文件具有偏移和长度信息的模式文件的固定平面文件的请求。我得到了所有的细节，但是当我开始进行分组时，我无法再进一步......任何帮助都非常感激，让我心烦意乱。

源平面文件

P01020 230039....
A30438 009090.....
A30439 009039.....
P02390 039438....
D03049 304830...
A30493 304030...
P30439 230300....

架构文件：

    <Schema>
<Purchase recordIdentifer="P">
    <FIELD1 length="5" offset="1" type="xs:string"/>
    <FIELD2 length="6" offset="8" type="xs:string"/>
</Purchase>
<Account recordIdentifer="A">
    <FIELD1 length="5" offset="1" type="xs:string"/>
    <FIELD2 length="6" offset="8" type="xs:string"/>
</Account>
<Deposit recordIdentifer="D">
    <FIELD1 length="5" offset="1" type="xs:string"/>
    <FIELD2 length="6" offset="8" type="xs:string"/>
</Deposit>

XSLT代码

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:param name="text-url" select="'test2014032901.txt'"/>
     <xsl:param name="file1" select="document('Schema.xml')"/>
    <xsl:output indent="yes"/>
    <xsl:template name="main">
        <xsl:variable name="text" select="unparsed-text($text-url)"/>
        <xsl:variable name="lines" as="element(line)*">
            <xsl:for-each select="tokenize($text,'\r?\n')[normalize-space()]">
                <line>
                    <xsl:value-of select="."/>
                </line>
            </xsl:for-each>
        </xsl:variable>
        <Root>
            <xsl:for-each-group select="$lines" group-starting-with="line[starts-with(., 'P')]">
            <Purchases>
                 <Purchase>
                            <xsl:for-each select="$file1/Schema/Purchase">
                            <xsl:for-each select="./*">
                                <xsl:element name="{name(.)}">
                                    <xsl:value-of select="substring($lines, ./@offset,./@length)"/>
                                </xsl:element>
                            </xsl:for-each>
                        </xsl:for-each>
               </Purchase>
            </Purchases>
            </xsl:for-each-group>
            <xsl:for-each-group select="$lines" group-starting-with="line[starts-with(., 'A')]">

                            <xsl:for-each select="./*">
                                <xsl:element name="{name(.)}">
                                    <xsl:value-of select="substring($lines, ./@offset,./@length)"/>
                                </xsl:element>
                            </xsl:for-each>
                        </xsl:for-each>
               </Account>
            </Accounts>
            </xsl:for-each-group>
            <xsl:for-each-group select="$lines" group-starting-with="line[starts-with(., 'D')]">
            <Deposits>
                 <Deposit>
                            <xsl:for-each select="$file1/Schema/Deposit">
                            <xsl:for-each select="./*">
                                <xsl:element name="{name(.)}">
                                    <xsl:value-of select="substring($lines, ./@offset,./@length)"/>
                                </xsl:element>
                            </xsl:for-each>
                        </xsl:for-each>
               </Deposit>
            </Deposits>
            </xsl:for-each-group>
        </Root>
    </xsl:template>
</xsl:stylesheet>

输出XML如下所示

<Root>
    <Purchases>
        <Purchase>
            <Field1>01020</Field1>
            <Field2>230039</Field2>
        </Purchase>
        <Purchase>
            <Field1>02390</Field1>
            <Field2>039438</Field2>
        </Purchase>
        <Purchase>
            <Field1>30439</Field1>
            <Field2>230300</Field2>
        </Purchase>
    </Purchases>
    <Accounts>
        <Account>
            <Field1>30438</Field1>
            <Field2>009090</Field2>
        </Account>
        <Account>
            <Field1>01020</Field1>
            <Field2>230039</Field2>
        </Account>
        <Account>
            <Field1>01020</Field1>
            <Field2>230039</Field2>
        </Account>
    </Accounts>
    <Deposits>
        <Deposit>
            <Field1>03049</Field1>
            <Field2>304830</Field2>
        </Deposit>
    </Deposits>
</Root>

非常感谢任何帮助!!!。

Answer 1

我不确定我是否理解使用for-each-group，似乎至少对于购买而言

        <Purchases>
            <xsl:for-each select="$lines[starts-with(., 'P')]">
                <Purchase>
                    <xsl:variable name="line" select="."/>
                    <xsl:for-each select="$file1/Schema/Purchase/*">
                        <xsl:element name="{name(.)}">
                            <xsl:value-of select="substring($line, @offset, @length)"/>
                        </xsl:element>
                    </xsl:for-each>
                </Purchase>
            </xsl:for-each>
        </Purchases>

足以给予

   <Purchases>
      <Purchase>
         <FIELD1>P0102</FIELD1>
         <FIELD2>230039</FIELD2>
      </Purchase>
      <Purchase>
         <FIELD1>P0239</FIELD1>
         <FIELD2>039438</FIELD2>
      </Purchase>
      <Purchase>
         <FIELD1>P3043</FIELD1>
         <FIELD2>230300</FIELD2>
      </Purchase>
   </Purchases>
