Question

我从xml文档中获取了一个名为XmlNodeList的列表。我可以使用GetElementsByTagName获取innertext值。但我需要从内部标签读取值。想要阅读＆＃34; USD＆＃34; in＆＃34; Currency CrossOrder =＆＃34; 0＆＃34; KOD =＆＃34; USD＆＃34;货币代码=＆＃34; USD＆＃34;＆＃34;一部分。

<Currency CrossOrder="0" 
          Kod="USD" 
          CurrencyCode="USD">
    <Unit>1</Unit>
    <Isim>ABD DOLARI</Isim>
    <CurrencyName>US DOLLAR</CurrencyName>
    <ForexBuying>4.0707</ForexBuying>
    <ForexSelling>4.0780</ForexSelling>
    <BanknoteBuying>4.0678</BanknoteBuying>
    <BanknoteSelling>4.0841</BanknoteSelling>
    <CrossRateUSD />
    <CrossRateOther />
</Currency>
<Currency CrossOrder="1" 
          Kod="AUD" 
          CurrencyCode="AUD">
    <Unit>1</Unit>
    <Isim>AVUSTRALYA DOLARI</Isim>
    <CurrencyName>AUSTRALIAN DOLLAR</CurrencyName>
    <ForexBuying>3.1389</ForexBuying>
    <ForexSelling>3.1594</ForexSelling>
    <BanknoteBuying>3.1245</BanknoteBuying>
    <BanknoteSelling>3.1784</BanknoteSelling>
    <CrossRateUSD>1.2938</CrossRateUSD>
    <CrossRateOther />
</Currency>

Answer 1

对于$primaryKey = $row['nameOfPrimaryKeyColumn'];，XmlReader是<Currency CrossOrder="0" Kod="USD" CurrencyCode="USD">类型的节点。

Element是此节点中的属性。如果您想获得＆＃34; USD＆＃34;，您将获得CurrencyCode属性的值。

尝试CurrencyCode方法。
