鉴于此记录结构，我的正确Xpath表达式

base is / products / product

仅选择category =“Wit”
仅选择非空品牌字段的产品记录

    <product>
        <productID>?7804407001751?</productID>
        <name>?Name value?</name>
        <price currency="EUR">?11.?24?</price>
        -<productURL>
            product url value
        </productURL>
        -<imageURL>
            product img url value?
        </imageURL>
        -<description>
            description value
        </description>
        -<categories>
            <category path="Wit">?Wit?</category>
        </categories>
        -<additional>
            <field name="delete">?false?</field>
            <field name="brand">?Amaral?</field>
            +<field name="short_description"></field>
            <field name="deliveryTime">?5 werkdagen?</field>
            <field name="deliveryCosts">?5.?95?</field>
            +<field name="imageURL_2"></field>
            +<field name="imageURL_3"></field>
        </additional>
    </product>

Answer 1

试试这些......

1）/products/product[categories/category/@path='Wit']

2）/products/product[additional/field[@name='brand'][normalize-space()]]

如果你想要两者合并：

/products/product[categories/category/@path='Wit' and additional/field[@name='brand'][normalize-space()]]

Answer 2

base is / products / product

1）仅选择category =“Wit”
的产品记录

使用：

../product[categories/category/@path = 'Wit']

2）仅选择非空品牌字段的产品记录

使用：

../product[additional/field[@name='brand' and normalize-space()]]

Answer 3

<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="product">
With 'Wit':
<xsl:value-of select="../product[categories/category/@path = 'Wit']/name"/>
with brandname:
<xsl:value-of select="../product[additional/field[@name='brand' and normalize-space()]]/name"/>
</xsl:template>
</xsl:stylesheet>

请注意，我只返回产品的名称。如果您想要退回所有产品详细信息，只需删除＆＃39; / name＆＃39;来自选择＆＃39;的价值。
