如何用xpath定位符合多个属性条件的节点集

查找所有book节点（xpath: //book），对每个节点分析其属性，MSXML都有相关的函数

MSXMLNS::IXMLDOMNodeListPtr pNodeList = NULL;

MSXMLNS::IXMLDOMNamedNodeMapPtr methodpAttrs = NULL;

MSXMLNS::IXMLDOMNodePtr pmethodAttrItem;

MSXMLNS::IXMLDOMNodePtr psNode;

MSXMLNS::IXMLDOMNodePtr requiredNode;

pNodeList = m_pDomDoc->selectNodes((_bstr_t)"//book");

int num = pNodeList->Getlength();

long nCount = 0;

for(int i=0;i<num;i++)

{

psNode=pNodeList->Getitem(i);//取得psNode的节点值

psNode->get_attributes(&methodpAttrs);

methodpAttrs->get_length(&nCount);

for(int nmethod = 0; nmethod < nCount; nmethod++) //属性值的循环

{

methodpAttrs->get_item(nmethod,&pmethodAttrItem);

CString strgetName = FromBSTR((_bstr_t)pmethodAttrItem->nodeName);

CString strgetValue = FromBSTR((_bstr_t)pmethodAttrItem->nodeTypedValue);//得到属性值后进行相应的 *** 作

}

}

$xmlDoc = new DOMDocument;

$xmlDoc -> load($xml_resource);

$xpath = new DOMXPath($xmlDoc);

//$advert_path = '/root/advert[@id="1"]';

$statue_path = '/root/advert/status';

//$advert = $xpath -> query($advert_path) ->item(0);

$replaceNodeOld = $xpath -> query($statue_path) ->item(0);

$replaceNodeNew = = $xmlDoc -> createElement('person', 'fff');//改变成它

$replaceNodeOld = $replaceNodeOld -> item(0)->parentNode->replaceChild($replaceNodeNew, $replaceNodeOld ->item(0));
