Xml 基于多重分组和加法终止的muenchian和

我想使用一些xslt和xml获得更好的xml文件 请提供XSLT1.0支持。非常感谢

<!-- entry xml -->
    <Pallets>
    <Pallet>
    <PalletNumber>2</PalletNumber>
    <Product>1</Product>
    <Quantity>2</Quantity>
    </Pallet>
    <Pallet>
    <PalletNumber>2</PalletNumber>
    <Product>1</Product>
    <Quantity>4</Quantity>
    </Pallet>
    <Pallet>
    <PalletNumber>2</PalletNumber>
    <Product>2</Product>
    <Quantity>1</Quantity>

    <Pallet>

我需要汇总每个托盘编号和产品的数量（参见第一个节点 下面）。此外，序列号也需要在 基于xml中第一次出现的palletnumber值。结果应 看起来像：

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

<!-- upgraded xml --> 
    <Pallets><Pallet>
    <PalletNumber>2_1</PalletNumber>
    <Product>1</Product>
    <Quantity>6</Quantity>
    </Pallet>
    <Pallet>
    <PalletNumber>2_2</PalletNumber>
    <Product>2</Product>
    <Quantity>1</Quantity>
    </Pallet>
    <Pallet>
    <PalletNumber>3_1</PalletNumber>
    <Product>1</Product>
    <Quantity>2</Quantity>
    </Pallet>
    <Pallet>
    <PalletNumber>4_1</PalletNumber>
    <Product>2</Product>
    <Quantity>2</Quantity>
    </Pallet></Pallets>

不能100%确定新的

托盘编号的逻辑是否正确（这里是凌晨3:00），但是下面的XSLT 1.0返回了所需的输出和给定的输入

XML输入

<Pallets>
    <Pallet>
        <PalletNumber>2</PalletNumber>
        <Product>1</Product>
        <Quantity>2</Quantity>
