XSLT 1.0-使用定界符在for-each循環內拆分字段

Question

我有一個需要轉換的XML文件。 我能夠構建在沒有分隔符的第一種情況下可以工作的XSLT文件，但是現在在第二種情況下，有一個需要分隔成兩個字段的定界符+字段。

這是第二種情況下的源XML。 百分號+位於“組/組/詳細信息/部分/字段/'FieldName='{STATION.Comments}'/值”字段中：

<?xml version="1.0" encoding="UTF-8"?>

這是我未添加定界符的第一種情況下的XSLT 1.0文件：

這是期望的輸出，使用分隔符分隔字段。 使用定界符來創建兩個字段，其中一個用於itemid，第二個用於SalesUNIT：

<Envelope xmlns="http://schemas.microsoft.com/dynamics/2011/01/documents/Message">
    <Header>
        <Company>tgs</Company>
        <Action>http://schemas.microsoft.com/dynamics/2008/01/services/SalesOrderService/create</Action>
    </Header>
    <Body>
        <MessageParts>
            <SalesOrder xmlns="http://schemas.microsoft.com/dynamics/2008/01/documents/SalesOrder">
                <SalesTable class="entity">
                    <CustAccount>TRW Automotive</CustAccount>
                    <PurchOrderFormNum>PO</PurchOrderFormNum>
                    <ReceiptDateRequested>2019-08-01</ReceiptDateRequested>
                    <SalesLine class="entity">
                        <ItemId>SWBP169-10</ItemId>
                        <SalesQty>47</SalesQty>
                        <SalesUnit>EA</SalesUnit>
                    </SalesLine>
                    <SalesLine class="entity">
                        <ItemId>Y19CFC</ItemId>
                        <SalesQty>18</SalesQty>
                        <SalesUnit>EA</SalesUnit>
                    </SalesLine>
                </SalesTable>
            </SalesOrder>
        </MessageParts>

提前致謝。

Answer 1

如果源將始終包含兩個用+分隔的值，則可以使用以下方法提取第一個值：

substring-before(Value, '+')

第二個是：

substring-after(Value, '+')
