爲什麼我從DOM解析器中獲取額外的節點內容

Question

我想從modules節點獲取文本上下文，但它會從樹中返回額外的值。

<modules>New Enterprise Development 
    <credits>15</credits> 
    <level>M</level> 
    <core_or_optional>core</core_or_optional> 
</modules> 
<modules>Computing Law, Contracts and Professional Responsibility 
    <credits>15</credits> 
    <level>M</level> 
    <core_or_optional>core</core_or_optional> 
</modules> 

解析代碼：

for (int j=0; j<NodelistB.getLength(); j++){ 
    Node xPathNode = NodelistB.item(j); 
    Element xPath = (Element)xPathNode; 
    targetNodeContent = xPath.getTextContent(); 
    targetNode = xPath.getTagName(); 
    System.out.println(targetNodeContent) ; 
    System.out.println() ;  
} 

我預期的返回值是：

New Enterprise Development 
Computing Law, Contracts and Professional Responsibility 

但它打印出以下幾點：

New Enterprise Development 
15 
M 
core     

Computing Law, Contracts and Professional Responsibility 
15 
M 
core 

Answer 1

閱讀javadoc的getTextContent()：

此屬性返回此節點及其後代的文本內容。

Answer 2

您的XML無效（或不如您想象的那樣）。你應該使用這些格式之一：

<modules name="New Enterprise Development"> 
    <credits>15</credits> 
    <level>M</level> 
    <core_or_optional>core</core_or_optional> 
</modules> 

<modules> 
    <name>New Enterprise Development</name> 
    <credits>15</credits> 
    <level>M</level> 
    <core_or_optional>core</core_or_optional> 
</modules> 

（也，你應該使用「模塊」，而不是「模塊」）
