我有一个xml文件如下：

<bookstore>
    <book category="xyz">
        <title lang="en">some</title>
        <author>abc</author>
        <year>2005</year>
        <price>30.00</price>
    </book>
    <book category="children">
        <title lang="en">Harry Potter </title>
        <author>Rowling</author>
        <year>2005</year>
        <price>29.99</price>
    </book>
</bookstore>

我需要 book 的子节点与 book 的顺序相同（没有父子节点）。生成的 xml 应如下所示：

<bookstore>
    <book category="xyz">
    <title lang="en">some</title>
    <author>abc</author>
    <year>2005</year>
    <price>30.00</price>
    </book>
    <book category="children">
    <title lang="en">Harry Potter </title>
    <author>Rowling</author>
    <year>2005</year>
    <price>29.99</price>
    </book>
</bookstore>

相同的代码片段如下：

pXMLEventList = pXMLDoc->getElementsByTagName("book");
int numEvent = pXMLEventList->Getlength();
for(int evntCount = 0; evntCount < numEvent; evntCount++)
{   

    /*Read the xml file in a away wherein all the childnodes   
    at same level as of root node */
    pXMLEventDoc = pXMLEventList->item[evntCount];
    pXMLNodeList = pXMLEventDoc->getElementsByTagName("*");
    int count = pXMLNodeList->Getlength();
}

但 pXMLEventDoc 始终为 NULL。有人可以帮助我吗？

谢谢
