我想使用Pyton修改XML文件。
我想改变：
<socket-binding name="http" port="8280"/>
成：
<socket-binding name="http" port="8080"/>
我该怎么做？
XML如下：
<?xml version='1.0' encoding='UTF-8'?>

更新
我曾尝试过这样做，但仍然没有运气
tree=ET.parse("standalone-full.xml")
root=tree.getroot()
element=root.find('.//socket-binding[@name="http"]')
element.attrib['port'] = '8080'
更新2：
使用.// {た：jboss：domain：1.2}}套接字[@name="http“]（信用到@ sk11）我现在能够到达端口，但我不知道如何保存当前xml的更新值。
非常感谢
答案 0 :(得分：2)
从标准库xml.etree.ElementTree通过find the element加载，然后更改port attribute value。然后，转储修改后的树to string（或write to file）：
import xml.etree.ElementTree as ET
data = """
<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
<socket-binding name="management-native" interface="management" port="${jboss.management.native.port:9999}"/>
<socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>
<socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9443}"/>
<socket-binding name="ajp" port="8009"/>
<socket-binding name="http" port="8280"/>
</socket-binding-group>
"""
tree = ET.fromstring(data)
element = tree.find('.//socket-binding[@name="http"]')
element.attrib['port'] = '8080'
print ET.tostring(tree)
打印：
<socket-binding-group default-interface="public" name="standard-sockets" port-offset="${jboss.socket.binding.port-offset:0}">
<socket-binding interface="management" name="management-native" port="${jboss.management.native.port:9999}" />
<socket-binding interface="management" name="management-http" port="${jboss.management.http.port:9990}" />
<socket-binding interface="management" name="management-https" port="${jboss.management.https.port:9443}" />
<socket-binding name="ajp" port="8009" />
<socket-binding name="http" port="8080" />
</socket-binding-group>
注意，port为8280，已成为8080。
.//socket-binding[@name="http"]是一个xpath expression，可以匹配任何socket-binding代码，name属性等于http。
