请教DOM查询XML的两个小问题,100分

[snake1122]

1。关于selectSingleNode\selectNodes的用法，怎么老是报异常？
pNodetest = docPtr->selectSingleNode("//fo:simple-page-master");
2。如何用节点的属性名和属性值来查询该节点？
有兄台说这么查，没调通：
pNodetest = docPtr->selectSingleNode("//fo:simple-page-master[@master-name='KimeiBodyPage']");

//怎么老是报异常？

what kind of 异常？

what version of MSXML are you using? did you forget to use setProperty to set SelectionNamespace? see

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/xmlsdk30/htm/xmpro2nd_selectionnamespaces.asp


xmldoc.setProperty("SelectionNamespaces",
"xmlns:fo='http://myserver.com'
xmlns:otherNS='http://yourserver.com'");

MSXML4,IE6自带的那个，
我只是读取已有的xml文件，已经有该属性，

你的docPtr初始化是否正确呀，或者命名空间fo定义是否正确

[snake1122]

初始化正确的，fo:...是节点名

void readDocument(IXMLDOMDocument2Ptr& pXMLDoc)
{
try
{
IXMLDOMNodePtr pDataViews = NULL;
IXMLDOMElementPtr pRootElem = NULL;

// Get root element
EVAL_HR(pXMLDoc->get_documentElement(&pRootElem));
pDataViews = pRootElem->selectSingleNode("DataViews");
pDataViews = pDataViews->nextSibling;
if(pDataViews)
{
IXMLDOMNodePtr pViewSQL = pDataViews->selectSingleNode("ViewSQL");
if(pViewSQL)
{
printf("node text:%s\n", (LPCTSTR)pViewSQL->text);
}
}
pDataViews = pDataViews->nextSibling;
//IXMLDOMNodePtr pViewSQL = pRootElem->selectSingleNode("DataViews/ViewCols/ColName");
IXMLDOMNodePtr pViewSQL = pDataViews->selectSingleNode("ViewCols/ColName");
_bstr_t bs_text;
IXMLDOMNodePtr pLastNode;
while(pViewSQL)
{
if(pViewSQL)
pLastNode = pViewSQL;
bs_text = pViewSQL->nodeName;
pViewSQL = pViewSQL->nextSibling;
}
IXMLDOMNodePtr pNameAttribute = pLastNode->attributes->getNamedItem("Name");
if(pNameAttribute)
{
printf("name attribute of last element:%s\n", LPCTSTR(pNameAttribute->text));
}
}
catch(...)
{
printf("read failed\n");
}
}
