python 2.7 - XML parsing to access tags -


i have xml file, fetch tags, edit necessary element , write new file (updated xml). 

<vdu xmlns="test:file"> <lsm>     <m-id>v1</m-id>     <name>v1</name>     <communication>bi</communication>     <states>         <s-name>stage1</s-name>         <state>             <s-type>defaultstate</s-type>             <s-func>                 <p-name>pkgname</p-name>                 <f-list>                     <f-name>funcname</f-name>                     <f-arg>{&amp;}</f-arg>                 </f-list>             </s-func>         </state>         <lib-path>libpath</lib-path>         <e-list>             <e-name>noevent</e-name>             <event>                 <nss>inc</nss>                 <nfs>inc</nfs>                 <actions>                     <p-name>pkgname</p-name>                     <f-list>                         <f-name>tof</f-name>                         <f-arg></f-arg>                     </f-list>                 </actions>             </event>         </e-list>

however not able text xml. tried couple of things below.

import xml.etree.elementtree et root = et.parse(r'c:\users\sample\file.xml').getroot()  child in root:     print child.tag     child in child.iter('s-type'):         print child

output: 

 <element '{est:file}lsm  []

also, tried lxml(still exploring), didnt expected answer. appreciated.

root.xpath("//lsm/states/e-list/e-name/text()")

output:

[]

however able access values root[0][0].text

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
