変数に含まれるテキスト文字列を XML ノードに変換する必要があります。出力 XML へのマッピングは、「mapping.xml」という名前のファイルによって決定されます。ビット操作(ビットが1かどうかのチェック)があります。
mapping.xml
<Root>
<field no="2" charlength="2">variable</field>
<field no="3" total="4">fixed</field>
<field no="21" charlength="2">
<subfield no="1" total="3">fixed</subfield>
<subfield no="2" charlength="2" idcode="ABC">variable</subfield>
</field>
<field no="63" charlength="2">
<format1>
<subfield no="1" total="3">fixed</subfield>
</format1>
<format2>
<subfield no="1" total="3">fixed</subfield>
<subfield no="2" total="7">fixed</subfield>
</format2>
<format3>
<subfield no="1" total="3">fixed</subfield>
<subfield no="2" total="7">fixed</subfield>
<subfield no="3" total="6">fixed</subfield>
</format3>
</field>
</Root>
1) The xml will have 64 'field' elements. For a sample, i have included 3 to four fields here, in the mapping xml
2) Always the string will follow the order, fields 1 to 64 in ascending.
3) The fields can be fixed or variable. Fixed means the string will be of number of characters, determined by the charlength attribute corresponding to a field
4) Some fields can have subfields
5) The subfields can have fixed and variable. All fixed ones occur first, followed by the variable subfields.
6) A field which has subfields, fixed ones(subfields) always occur, fixed one does not have idcode attributes.
7) A Field which has subfields, variable ones(subfields), start with 'idcode' attribute, followed by the charlength(determined by the charlength attribute)
8) The subfield idcodes and lengths always occur, however the data may or may not be present, depending on char length(if characters determined by charlength is 0, then the data will not be there)
9) Field no 63 is an exception, where the character length determines the format of the field. If the character is 03(number of chars 2), it is format1. If it is 10, format2, then if it is 16, format3.
9) The occurence of fields, determined by bit positions(0 means no occurence, 1 stands for occurence)
10)The bit positions is determined by another variable which holds a hex value(8 bytes - 64 bits)
私の六角形は次のとおりです。
<xsl:variable name="hex" select="'6000080000000000'"/><!--16 digits, each digit represents fourbits-->
as illustrated below
0110 0000 0000 0000 0000 1000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000
6 0 0 0 0 8 0 0 0 0 0 0 0 0 0 0
この 16 進数は、フィールド 2、3、および 21 が存在することを示しています。これらの位置として、1(セット) があります。
文字列変数が(私の入力)の場合
<xsl:variable name="inputstring" select="'013112316145ABC0812345678'"/>
上記の文字列 16 (1123 の後) は、フィールド 21 の文字の長さを表します。
私の望む出力:
<Root>
<field2>3</field2>
<!--value is 3 as the charlength is 2(which is 01)-->
<field3>1123</field3>
<!--field3 value is 1123 as it is fixed, total length of 4-->
<field21>
<subfield1>145</subfield1>
<!--subfield1 should be 145 as it is fixed length of total 3 chars-->
<subfield2>12345678</subfield2>
<!--subfield2 starts with 'ABC', has length 08 chars-->
</field21>
</Root>
最後に、XML ノードを 16 進数の文字列に戻すにはどうすればよいでしょうか。
