我有以下xml文件suing tcl脚本语言. workarea poller name="Poller1" pollerAttribute loc="c:\abc" username="abc" password="xxx" value123/value /pollerAttribute /poller poller name="Poller2" pollerAttribute loc="c:\def" username="def"
<workarea>
<poller name="Poller1">
<pollerAttribute loc="c:\abc" username="abc" password="xxx">
<value>123</value>
</pollerAttribute>
</poller>
<poller name="Poller2">
<pollerAttribute loc="c:\def" username="def" password="xxx">
<value>345</value>
</pollerAttribute>
</poller>
.....
</workarea>
在这里,我想用Poller名称读取每个tage,然后更改密码=“xxx”.
我是tcl脚本语言的新手.
任何帮助对我来说都很棒.
谢谢你.
package require tdom
set filename "thefile.xml"
set xpath {//pollerAttribute[@password]}
# Read in
set f [open $filename]
set doc [dom parse [read $f]]
close $f
set root [$doc documentElement]
# Do the update of the in-memory doc
foreach pollerAttr [$root selectNodes $xpath] {
$pollerAttr setAttribute password "theNewPassword"
}
# Write out (you might or might not want the -doctypeDeclaration option)
set f [open $filename "w"]
$doc asXML -channel $f -doctypeDeclaration true
close $f
就是这样. (您可能需要更加谨慎地选择具有正确密码属性的元素,并以更复杂的方式提供替换密码,但这些都是狡猾的.)
