Notes for XML Element operations

In IE, if the version is earlier than 9, you cannot directly set Custom Attributes. You must use the setattribute method. other browsers do not have this problem.

 
// For example, sizzleCodeAn error occurs in ie xml. You cannot directly use el. AAA = "BBB" If (parent & (parent [expando]! = Donename |! ELEM. nodeindex) {COUNT = 0; For (node = parent. firstchild; node = node. nextsibling) {If (node. nodetype = 1) {node. nodeindex = ++ count ;}} parent [expando] = donename ;}
 

XML getelementsbytagname. If the tag name has a namespace (separated by ":" In other words), opera, chrome, and Safari cannot be found. Firefox and IE can be used. In this case, you need to use the getelementsbytagnamens and lookupnamespaceuri APIs. The following describes how to find the tagname:

Function getelementsbytagname (tagname, Els, flag_xml) {VaR method = "getelementsbytagname", elems = [], uniqresult = {}, prefix if (flag_xml & tagname. indexof (":")> 0 & els. length & els [0]. lookupnamespaceuri) {var arr = tagname. split (":"); prefix = arr [0]; tagname = arr [1]; method = "getelementsbytagnamens"; prefix = els [0]. lookupnamespaceuri (prefix);} switch (els. length) {Case 0: Return ELEM S; Case 1: // In ie67, if an input element with name length exists, the following all. Length returns this element, instead of the length value var all = prefix? Els [0] [Method] (prefix, tagname): els [0] [Method] (tagname) for (VAR I = 0, rI = 0, El; el = All [I ++];) {If (El. nodetype = 1) {// prevents mixed comments node elems [ri ++] = El} return elems; default: for (I = 0, rI = 0; el = els [I ++];) {var nodes = prefix? El [Method] (prefix, tagname): El [Method] (tagname) for (var j = 0, node; node = nodes [J ++];) {var uid = Dom. getuid (node); If (! Uniqresult [uid]) {uniqresult [uid] = elems [ri ++] = node ;}} return elems ;}}
