xml 是否可以通过某种方式进行编辑？

Question

我不确定是否可以完成以下任务。我已经完成了它的第一部分，所以我在这里放了一些我想进一步使用的代码。这个问题可能有点长，抱歉。我想编辑一个 xml 文件，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<notes version="1">
    <labels>
        <label id="0" color="80FF80">BadReg</label>
        <label id="1" color="FFFF40">GoodReg</label>
        <label id="2" color="8000FF">Bluffer</label>
        <label id="3" color="10FF10">Fish</label>
        <label id="4" color="1080FF">Loose</label>
        <label id="5" color="30DBFF">Semi-Loose</label>
        <label id="6" color="0000FF">Nit</label>
        <label id="7" color="FF9F48">Tight</label>
        <label id="8" color="C0C0C0">Undefined</label>
    </labels>
    <note player="00aquitis00" label="7" update="1429834930"></note>
    <note player="01 LUGAR" label="8" update="1429834930"></note>
    <note player="07 Star 07" label="4" update="1429834930"></note>
    <note player="109185" label="6" update="1429834930">Some notes are here</note>
    <note player="1111167" label="8" update="1429834930">And some there...</note>
</notes>

我想在上面的 *.xml 文件中编辑某些玩家的 ID 和他们的标签编号。首先我有一个 players.txt 和一个 ReportExport.csv 文件，它们看起来像这样，CSV:

"","Player","VPIP","PFR","Hands","Players"
"2532|100|""Seikei""&5RS","""Seikei""&5RS","20.45","12.50","88","5.65"
"4265|100|#23Mattingly","#23Mattingly","41.94","25.81","33","5.55"
"2748|100|#PachnacyBak","#PachnacyBak","11.54","10.00","52","5.44"
"6|100|eagle189","eagle189","20.60","13.60","73,561","5.55"

TXT:

player1         badreg
player2         badreg
player3         bluffer
player4         bluffer

第一步，我从 *.txt 和 *.csv 文件中获取数据（我想要使用的数据）。 AWK代码：

BEGIN   {
                update = 1429834930 }

FILENAME == "players.txt"   {

                FS = "\t\t"

                playertype = ;

                if (playertype == "badreg") {badregs[]++};
                if (playertype == "bluffer") {bluffers[]++};
                if (playertype == "fish") {fishes[]++};
                if (playertype == "goodreg") {goodregs[]++};
                next }

(FILENAME == "ReportExport.csv") && (FNR != 1)  {

                FS = "\",\""

                name = ;
                vpip = ;
                pfr = ;
                hands = ;
                avgp = substr(, 1, (length()-1));

                if (name == "") {name = "Name"}

                gsub(/&/, "\&amp;", name)
                gsub(/</, "\&lt;", name)
                gsub(/>/, "\&gt;", name)
                gsub(/\"\"\"/, "\"\"", name)
                gsub(/\"\"/, "\"", name)
                gsub(/\"/, "\&quot;", name)

                gsub(/,/, "", hands)

                label = 8;

                if ((hands >= 100) && ((vpip / 1.40) <= (100 / avgp))) {label = 7}  #Tight
                if ((hands >= 18) && ((vpip / 1.00) <= (100 / avgp))) {label = 7}   #Tight
                if ((hands >= 100) && ((vpip / 1.25) <= (100 / avgp))) {label = 6}  #Nit
                if ((hands >= 24) && ((vpip / 2.20) >= (100 / avgp))) {label = 5}   #Semi-Loose
                if ((hands >= 15) && ((vpip / 3.00) >= (100 / avgp))) {label = 4}   #Loose
                if ((hands >= 30) && ((vpip / 2.60) >= (100 / avgp))) {label = 4}   #Loose

                if ((hands >= 24) && ((vpip / 2.60) >= (100 / avgp)) && ((pfr/vpip) <= 0.2)) {label = 3}    #Fish

                if (name in fishes)     {label = 3} #Fish
                if (name in bluffers)   {label = 2} #Bluffer
                if (name in goodregs)   {label = 1} #GoodReg
                if (name in badregs)    {label = 0} #BadReg
            }

在这一点之后，当我终于得到了播放器的正确标签类型时，我想在 *.xml 文件中进行搜索，如果可以找到播放器，那么我'我想更新他的标签号，如果找不到他，我想在其他玩家旁边打印一行到 *.xml 文件中，如下所示：

printf("\t<note player=\"%s\" label=\"%s\" update=\"%s\"></note>\n", name, label, update)

然后保存*.xml文件，在处理csv文件时逐行重复此操作。在第一种情况下，如果可以找到播放器，重要的是不要替换 *.xml 文件中的整行，只需更新标签，因为有些播放器也可以包含一些注释（比如在示例代码），如果我们替换整行，它将丢失。所以真正的问题是，这些替换能否首先完成？如果可以的话，如果有人能告诉我应该从哪里继续，我将不胜感激：）当然，如果有更好的方法来代替逐行保存和搜索，我很想听听。

使用TXR的解决方案：

$ txr update.txr 
<?xml version="1.0" encoding="UTF-8"?>
<notes version="1">
    <labels>
        <label id="0" color="80FF80">BadReg</label>

        <label id="3" color="10FF10">Fish</label>
        <label id="4" color="1080FF">Loose</label>
