爲什麼我爲xslt

中的每條語句接收相同的輸出我試圖將xml文件轉換爲JSON。到目前爲止，我有這個爲什麼我爲xslt

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >

我的問題是，它打印關閉每個迴路同樣的事情。我只打印出它遇到的第一件事，並反覆做這件事。 Here就是我想要的一個例子，我不能認爲有區別。

你有'materialcode'兩次：一次是'sequence'的標籤，一次是'materialcode'。 –

我只打印出它碰到的第一件東西，並重復執行。

這樣做是因爲你反覆選擇了同樣的東西。

以//開頭的XPath表達式從根開始選擇整個文檔中的所有引用節點。並且（在XSLT 1.0中）xsl:value-of返回所選集合中第一個節點的值。

你不發表您預期的結果，所以我只能猜測你想要做的事，如：

<xsl:template match="batch"> 
    <xsl:for-each select="//batchitem">  
{ 
      "load_id" : "<xsl:value-of select="//batch/code"/>" 
      "amount" : "<xsl:value-of select="//batch/amount"/>" 
      "weighlistfactor" : "<xsl:value-of select="//batch/weighlistfactor"/>" 
      "watercorrection" : "<xsl:value-of select="//batch/watercorrection"/>" 
      "materialcode" : "<xsl:value-of select="//batch/sequence"/>" 
      "code" : "<xsl:value-of select="//batch/deliverynote/code"/>" 
      "materialcode" : "<xsl:value-of select="materialcode"/>" 
      "materialname" : "<xsl:value-of select="materialname"/>" 
    } 
    </xsl:for-each> 
</xsl:template>

其中 materialcode和 materialname的值由相對 XPath表達式檢索，從開始

目前的batchitem節點。
