Question

我需要在NativeDescription中通过在XSLT中循环来选择Credit_Term_Code="4"值：

<Credit_code_parents>
  <Credit_Term_parent Credit_Term_Code="1" NativeDescription="Letter of Credit" EnglishDescription="Letter of Credit" />
  <Credit_Term_parent Credit_Term_Code="2" NativeDescription="Cash on Delivery" EnglishDescription="Cash on Delivery" />
  <Credit_Term_parent Credit_Term_Code="3" NativeDescription="Contract" EnglishDescription="Contract" />
  <Credit_Term_parent Credit_Term_Code="4" NativeDescription="Net" EnglishDescription="Net" />
  <Credit_Term_parent Credit_Term_Code="5" NativeDescription="Contract" EnglishDescription="Contract" />
  <Credit_Term_parent Credit_Term_Code="6" NativeDescription="Net" EnglishDescription="Net" />
  <Credit_Term_parent Credit_Term_Code="7" NativeDescription="Contract" EnglishDescription="Contract" />
  <Credit_Term_parent Credit_Term_Code="8" NativeDescription="Net" EnglishDescription="Net" />
</Credit_code_parents>

Answer 1

要选择NativeDescription元素的Credit_Term_parent属性且Credit_Term_Code等于4，使用以下XPath之一：

如果Credit_Term_parent上方的祖先结构如图所示是固定的：

/Credit_code_parents/Credit_Term_parent[@Credit_Term_Code='4']/@NativeDescription

如果上面有可能变化的祖先结构 Credit_Term_parent（并假设提供的Credit_Term_Code在整个文档中是唯一的）：
```
//Credit_Term_parent[@Credit_Term_Code='4']/@NativeDescription
```

您要求使用XSLT循环代码：

<xsl:for-each select="/Credit_code_parents/Credit_Term_parent">
   <xsl:if test="@Credit_Term_Code=4">
     <xsl:value-of select="@Credit_Term_parent"/>
   </xsl:if>
</xsl:for-each>

或者，没有循环：

 <xsl:value-of
          select="//Credit_Term_parent[@Credit_Term_Code='4']/@NativeDescription"/>

...或者，使用上面＃1中的XPath而不是＃2中的XPath。

Answer 2

尝试以下

<xsl:for-each select="Credit_code_parents/Credit_Term_parent">
  <xsl:variable name="temp" select="@Credit_Term_Code"/>
  <xsl:if test="$temp='1'">
    <check>
      <xsl:value-of select="@NativeDescription"/>
    </check>
  </xsl:if>
</xsl:for-each>

希望有所帮助。
