感谢在SO this question帮助我的SO用户的帮助 我正在进行XML转换。
我使用转换逗号分隔值（DATE和QTY）撞墙的问题：
<?xml version="1.0" encoding="utf-8"?>
<results>
<recordset rowCount="68" fieldNames="ITEM,ECL,LEAD_TIME,QTY,DATE" type="**coldfusion.sql.QueryTable**">
<field name="ITEM">
<string>ITEM_A</string>
<string>ITEM_B</string>
<string>ITEM_C</string>
</field>
<field name="REV">
<string>A</string>
<string>B</string>
<string>C</string>
</field>
<field name="LEAD_TIME">
<string>10</string>
<string>15</string>
<string>25</string>
</field>
<field name="QTY">
<string>10,13,3</string>
<string>1,5,2</string>
<string>6,10,25</string>
</field>
</recordset>
<var name="DATE_LABELS">
<string>05-18,05-25,06-01</string>
</var>
</results>
分为：
<records>
<item_line>
<item>ITEM_A</item>
<rev>A</rev>
<lead_time>10</lead_time>
<values>
<qty date="05-18>10</qty>
<qty date="05-25>13</qty>
<qty date="06-01>3</qty>
</values>
</item_line>
<item_line>
<item>ITEM_B</item>
<rev>B</rev>
<lead_time>15</lead_time>
<values>
<qty date="05-18>1</qty>
<qty date="05-25>5</qty>
<qty date="06-01>2</qty>
</values>
</item_line>
<item_line>
<item>ITEM_C</item>
<rev>C</rev>
<lead_time>25</lead_time>
<values>
<qty date="05-18>6</qty>
<qty date="05-25>10</qty>
<qty date="06-01>25</qty>
</values>
</item_line>
</records>
是否可以用XSLT表达它？
我开始讨厌“设计”源xml架构的人......

我已将我提供的解决方案更新到您的其他问题：
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="/">
<records>
<!-- Just process the first field's children, to get the list of line items -->
<xsl:apply-templates select="/results/recordset/field[1]/*"/>
</records>
</xsl:template>
<!-- Convert each field child to a line item -->
<xsl:template match="field/*">
<item_line>
<!-- Then query all the fields for the value at this position -->
<xsl:apply-templates select="/results/recordset/field">
<xsl:with-param name="pos" select="position()"/>
</xsl:apply-templates>
</item_line>

<!-- Keep processing if there are more left -->

也许你下次可以在一个问题上问这块蛋糕，所以我们不必做两次，但我们走了！
