批处理 - 从 XML 文件中获取标签值

Question

I have this following XML file called "test.xml"

how can I get "Agent-name-8181818" value from "ragent-name" tag into a variable within a batch file?

<ragent>
    <type>ragent</type>
    <logger>
        <loglevel>log_warning</loglevel>
        <logger-dir>.</logger-dir>
    </logger>
    <additional-config>
        <logger-level>log_warning</logger-level>
    </additional-config>
    <configuration-info ts="26-02-2018_15-31-54">
        <apply-config-now>false</apply-config-now>
        <manual-settings-activation>Automatic</manual-settings-activation>
        <ragent-name ts="26-02-2018_15-31-54">Agent-name-8181818</ragent-name>
        <site ts="26-02-2018_15-31-54">site</site>
    </configuration-info>
</ragent>

Answer 1

With xpath.bat (does not require external binaries , just uses built-in windows capabilities):

call xpath test.xml "*//configuration-info/ragent-name"

to assign result to a variable:

for /f "tokens=* delims=" %%# in ('call xpath test.xml "*//configuration-info/ragent-name"') do set "reagent=%%#"

Answer 2

xmlstarlet sel -t -v "//ragent-name/text()" file.xml

Answer 3

As a batch-file line,

FOR /f "tokens=3delims=<>" %%a IN ('findstr "ragent-name" "q49011270.txt"') DO echo %%a

Where q49011270.txt is the file containing your data.

Naturally, you could assign the result to a variable instead of echo ing it...

You may solve this and other similar problems using the lookup capabilities of SETX command:

for /F "tokens=3" %%a in ('setx /F test.xml dummyVar /R 0^,2 ragent-name /D "<>"') do set "ragent=%%a" & goto continue
:continue
echo %ragent:~0,-1%

In this command:

setx /F test.xml dummyVar /R 0^,2 ragent-name /D "<>"

• /F test.xml is the file to process.
• dummyVar is a required variable.
• /R 0,2 ragent-name specify to search for "ragent-name" token in the file and, after found, return the token placed in the same line (0) and 2 tokens to right.
• /D "<>" indicate that tokens delimiters are "<" and ">" characters, besides spaces and tabs.

This method allows to extract tokens in lines above or below, or at left or right, from a target token in a very simple way. The only inconvenience is that the dummyVar variable remains in the environment with the value of the token found.

Answer 5

FOR /f "tokens=2 delims=>< " %%a IN ('TYPE config.xml ^| FIND ""') DO SET CONNECTION_STRING=%%a

config.xml is the path of the files connectionString is tag id connection_string is the variable name which you want to assign1

With the XML/HTML/JSON-parser xidel :

FOR /F "delims=" %A IN ('
  xidel -s test.xml -e "var:=//ragent-name" --output-format^=cmd
') DO %A

Output:

SET var=Agent-name-8181818
