c# - Reaching a specific Xmlnode from root using XPath with nested indexes -


i have xml string have specific node 

using system; using system.collections.generic; using system.collections; using system.linq; using system.web; using system.xml; using system.xml.xpath;

//xml string has xml content

string xmlstr = "<candidate>     <content>     <dob>14-jan-1976</dob>     <employers>       <employer>         <name>diane trucking</name>         <addresses>           <address>             <addressline1>1st street</addressline1>             <addressline2/>             <city>first city</city>             <state>fl</state>             <zip>12345</zip>           </address>           <address>             <addressline1>1st street</addressline1>             <addressline2/>             <city>second city</city>             <state>fl</state>             <zip>12346</zip>           </address>           <address>             <addressline1>3rd street</addressline1>             <addressline2/>             <city>third city</city>             <state>fl</state>             <zip>12347</zip>           </address>         </addresses>       </employer>       <employer>         <name>tom trucking</name>         <addresses>           <address>             <addressline1>4th street</addressline1>             <addressline2/>             <city>fourth city</city>             <state>fl</state>             <zip>12348</zip>           </address>           <address>             <addressline1>5th street</addressline1>             <addressline2/>             <city>fifth city</city>             <state>fl</state>             <zip>12349</zip>           </address>           <address>             <addressline1>6th street</addressline1>             <addressline2/>             <city>sixth city</city>             <state>fl</state>             <zip>12340</zip>           </address>         </addresses>       </employer>     </employers>     </content>     </candidate>";

// create xml document 

        xmldocument xmldoc = new xmldocument();         xmldoc.loadxml(xmlstr);

navigator alternative testing

        xpathnavigator xpathnav = xmldoc.createnavigator();         xpathexpression expr = xpathexpression.compile("/candidate/content/employers['1']/employer['1']/addresses['1']/address");

expression read/target xml specific xml node

        xpathnodeiterator xpathit = xpathnav.select(expr);   if(xpathit == null) {

... xpathit.count 6

}  var xmlnodes1 = xmldoc.selectnodes("/candidate/content/employers['1']/employer['1']/addresses['1']/address");  (int = 0; < xmlnodes1.count; i++ )   {

...xmlnodes1.count = 6. returns 6 address nodes , expecting 3 nodes of "address" specific employers/employer/addresses/address

}

both xpathit xmlnodes1 return 6 "address" elements expected return 3 elements there 3 addresses employer

i wanted target element in xml root also, if can able update specific element.

appreciate thank you

try removing single quotes xpath:

var xmlnodes1 = xmldoc.selectnodes("/candidate/content/employers['1']/employer['1']/addresses['1']/address");

should be

var xmlnodes1 = xmldoc.selectnodes("/candidate/content/employers[1]/employer[1]/addresses[1]/address");

note single quotes around number 1 removed.

the predicate selecting first item [1]. using predicate ['1'] ignored selectnodes getting all nodes , not first.

java - How to specify maven bin in eclipse maven plugin? -

i have eclipse maven plugin coming on centos. how can execute maven command on linx like: mvn clean package [abigail@localhost ~]$ mvn bash: mvn: command not found how should specify path executable of maven plugin in eclipse? or have install maven seperately？ thanks. eclipse (m2e) have bundled central parts of maven inside eclipse plugin, why not detected, , not usable. investigation find correct way bootstrap it, have create launcher file manually. if want run maven outside of eclipse, far better off standalone version of maven. mvn command bootstrap maven runtime system correctly, , secondly, able use advice concerning use of maven. maven binaries quite stable, wouldn't need upgrade upgrade eclipse. you can subsequently switch eclipse use external installation if prefer.
