我正在尝试编辑一个 xml 文件并增加一个名为“pageindex”的属性值。

xml文件中的数据是这样的

?xml version="1.0" encoding="UTF-8"?>
<quer:query productCode="RC1700" model="http://www.taleo.com/ws/tee800/2009/01" projectedClass="Candidate" locale="en" alias="MainQuery" mode="T-XML" largegraph="true"
preventDuplicates="false" attributes="pageindex=1,pagingsize=350" 
xmlns:quer="http://www.taleo.com/ws/integration/query">
<quer:subQueries/><quer:projections>
<quer:projection><quer:field path="Number"/>
</quer:projection><quer:projection><quer:field path="FirstName"/> 

这是我创建的批处理脚本,但值“1”没有增加。

    @echo off
    setlocal EnableExtensions DisableDelayedExpansion
    
    rem // Define constants here:
    set "_FILE=pagexml" & rem // (input file; `%~1` is the first argument)
    set "_INI=<quer:query productCode="RC1700" model="http://www.taleo.com/ws/tee800/2009/01" projectedClass="Candidate" locale="en" alias="MainQuery" mode="T-XML" largegraph="true" preventDuplicates="false" attributes=" &
    set "_TAG=pageindex=" & rem // (opening tag)
    
    rem // Loop over all (non-empty) lines of the input file:
    (for /F "usebackq delims=" %%L in ("%_FILE%") do (
        rem // Store current line string:
        set "LINE=%%L"
        rem // Toggle delayed expansion to avoid troubles with `!`:
        setlocal EnableDelayedExpansion
        rem // Split off opening tag from line string:
        set "TEST=!LINE:*%_TAG%=!"
        rem // Check whether opening tag has been found:
        if not "!TEST!"=="!LINE!" (
            rem // Opening tag found, hence split off closing tag:
            for /F "tokens=1* eol=, delims=, " %%S in ("!TEST!") do (
                rem // Get extracted number and increment it:
                set /A "NUM=%%S+1"
            rem // Return rebuild line with incremented number:
                echo( !_INI!!_TAG!!NUM!^,%%T
            )
        ) else (
            rem // Opening tag not found, hence return original line:
            echo(!LINE!
        )
        endlocal
    ))>pageTmp.xml 
    
    
    copy /v /y "pageTmp.xml" "page.xml"

del "pageTmp.xml"

这是我运行蝙蝠时得到的输出。您可以看到属性“pageindex”没有返回任何值。

?xml version="1.0" encoding="UTF-8"?>
<quer:query productCode="RC1700" model="http://www.taleo.com/ws/tee800/2009/01" projectedClass="Candidate" locale="en" alias="MainQuery" mode="T-XML" largegraph="true"
preventDuplicates="false" attributes="pageindex=,pagingsize=350" 
xmlns:quer="http://www.taleo.com/ws/integration/query">
<quer:subQueries/><quer:projections>
<quer:projection><quer:field path="Number"/>
</quer:projection><quer:projection><quer:field path="FirstName"/>

我该如何解决?这也是我第一次使用批处理脚本!

第一个问题是您的搜索字符串_TAG=pageindex=
在 中使用它时set "TEST=!LINE:*%_TAG%=!",这会导致

==1,pagingsize=350"

等号加倍,因为 serach 表达式不能包含等号,所以总是用等号来分割查找和替换部分。
您搜索pageindex并将其替换为=

因此%%S包含==1set /a NUM===1+1失败

您可以通过更改delims=, delims=,= in来解决它

for /F "tokens=1* eol=, delims=,= " %%S in ("!TEST!") do (
