Question

我有一个包含XML数据的字符串变量，我希望在该XML的另一个元素中添加一个子属性。我在脑海中的一个解决方案是将此字符串转换为XML，然后通过XML.appendChild()方法将其转换为完成，但我不确定，因为我还没有尝试过。

var pli = '';
pli = '<product-lineitem>
            <net-price>70.00</net-price>
            <tax>4.66</tax>
            <gross-price>74.66</gross-price>
            <base-price>70.00</base-price>
            <lineitem-text>THE GOLD GODS Micro Jesus Piece Gunmetal Necklace</lineitem-text>
            <tax-basis>52.50</tax-basis>
            <position>1</position>
            <product-id>26809214001</product-id>
            <product-name>THE GOLD GODS Micro Jesus Piece Gunmetal Necklace</product-name>
            <quantity unit="">1.0</quantity>
            <tax-rate>0.08875</tax-rate>
            <shipment-id>00017006</shipment-id>
            <gift>false</gift>
            <custom-attributes>
                <custom-attribute attribute-id="defaultItemShipment">add-to-cart</custom-attribute>
            </custom-attributes>
            <price-adjustments>
                <price-adjustment>
                    <net-price>-17.50</net-price>
                    <tax>0.00</tax>
                    <gross-price>-17.50</gross-price>
                    <base-price>-17.50</base-price>
                    <lineitem-text>25% off Dresses</lineitem-text>
                    <tax-basis>0.00</tax-basis>
                    <promotion-id>25-off-dresses-test</promotion-id>
                    <campaign-id>25-off-dresses-test</campaign-id>
                </price-adjustment>
            </price-adjustments>
        </product-lineitem>'

正如您可以看到上面的字符串，我只想使用JAVASCRIPT在<coupon-id> somevalue </coupon-id>元素中插入<price-adjustment>属性。输出将如下：

<product-lineitem>
        <net-price>70.00</net-price>
        <tax>4.66</tax>
        <gross-price>74.66</gross-price>
        <base-price>70.00</base-price>
        <lineitem-text>THE GOLD GODS Micro Jesus Piece Gunmetal Necklace</lineitem-text>
        <tax-basis>52.50</tax-basis>
        <position>1</position>
        <product-id>26809214001</product-id>
        <product-name>THE GOLD GODS Micro Jesus Piece Gunmetal Necklace</product-name>
        <quantity unit="">1.0</quantity>
        <tax-rate>0.08875</tax-rate>
        <shipment-id>00017006</shipment-id>
        <gift>false</gift>
        <custom-attributes>
            <custom-attribute attribute-id="defaultItemShipment">add-to-cart</custom-attribute>
        </custom-attributes>
        <price-adjustments>
            <price-adjustment>
                <net-price>-17.50</net-price>
                <tax>0.00</tax>
                <gross-price>-17.50</gross-price>
                <base-price>-17.50</base-price>
                <lineitem-text>25% off Dresses</lineitem-text>
                <tax-basis>0.00</tax-basis>
                <promotion-id>25-off-dresses-test</promotion-id>
                <campaign-id>25-off-dresses-test</campaign-id>
                <coupon-id> somevalue </coupon-id>
            </price-adjustment>
        </price-adjustments>
    </product-lineitem>

感谢帮助。

你检查了XML类文档 - ＆gt; https://documentation.demandware.com/DOC2/topic/com.demandware.dochelp/DWAPI/scriptapi/html/api/class_TopLevel_XML.html?resultof=%22%61%70%70%65%6e%64%43%68%69%6c%64%22%20%22%61%70%70%65%6e%64%63%68%69%6c%64%22%20

他们举例说明了如何在类描述的顶部添加一些内容。

处理XML的最佳做法是处理xml文件。您必须首先使用XMLStreamReader来读取xml。在用XMLStreamWriter写一个新的后，添加你需要的信息。无法在xml文件中追加内容。

有关更多说明，请查看dw.io包的文档 - ＆gt; https://documentation.demandware.com/DOC2/topic/com.demandware.dochelp/DWAPI/scriptapi/html/api/package_dw_io.html
