如何解析*.cat fi

Question

我想解析this文件。这是一个样本片段。在

    '13138' => { 'REFERENCE' => '13138', 'NAME' => 'DRAPER Five 125mm Medium Grade Aluminium Oxide Sanding Discs', 'PRICE' => 108, 'MIN_QUANTITY_ORDERABLE' => 1, 'MAX_QUANTITY_ORDERABLE' => 0, 'OUT_OF_STOCK' => 0, 'DATE_PROMPT' => '', 'OTHER_INFO_PROMPT' => '', 'PRICING_MODEL' => 0, 'TAX_1' => '101=2000.00=0=', 'OPAQUE_SHIPPING_DATA' => '0.054', 'ALT_WEIGHT' => '', 'SHIP_SEPARATELY' => 0, 'SHIP_CATEGORY' => '', 'SHIP_SUPPLEMENT' => 0, 'SHIP_SUPPLEMENT_ONCE' => 0, 'HAND_SUPPLEMENT' => 0, 'HAND_SUPPLEMENT_ONCE' => 0, 'SHIP_QUANTITY' => 1, 'COST_PRICE' => 0, 'EXCLUDE_FROM_SHIP' => 0, 'ASSEMBLY_PRODUCT' => 0, 'STOCK_AISLE' => '', 'STOCK_RACK' => '', 'STOCK_SUB_RACK' => '', 'STOCK_BIN' => '', 'BARCODE' => '', 'REPORT_DESC' => '', 'PRICES' => {
    1 => [
        [0,108],
    ],
},
    'CUSTOMVARS' => 
        {
        },
'NO_ORDERLINE' => 0, 'AUTOSHIP' => 0, 'PRODUCT_GROUP' => -1, 'THUMBNAIL' => '', 'IMAGE' => '13138_694.jpg', 'ALSOBOUGHT' => [], 'RELATED' => [],  }, 
    '13139' => { 'REFERENCE' => '13139', 'NAME' => 'DRAPER Five 125mm Coarse Grade Aluminium Oxide Sanding Discs', 'PRICE' => 96, 'MIN_QUANTITY_ORDERABLE' => 1, 'MAX_QUANTITY_ORDERABLE' => 0, 'OUT_OF_STOCK' => 0, 'DATE_PROMPT' => '', 'OTHER_INFO_PROMPT' => '', 'PRICING_MODEL' => 0, 'TAX_1' => '101=2000.00=0=', 'OPAQUE_SHIPPING_DATA' => '0.066', 'ALT_WEIGHT' => '', 'SHIP_SEPARATELY' => 0, 'SHIP_CATEGORY' => '', 'SHIP_SUPPLEMENT' => 0, 'SHIP_SUPPLEMENT_ONCE' => 0, 'HAND_SUPPLEMENT' => 0, 'HAND_SUPPLEMENT_ONCE' => 0, 'SHIP_QUANTITY' => 1, 'COST_PRICE' => 0, 'EXCLUDE_FROM_SHIP' => 0, 'ASSEMBLY_PRODUCT' => 0, 'STOCK_AISLE' => '', 'STOCK_RACK' => '', 'STOCK_SUB_RACK' => '', 'STOCK_BIN' => '', 'BARCODE' => '', 'REPORT_DESC' => '', 'PRICES' => {

    'CUSTOMVARS' => 
        {
        },
'NO_ORDERLINE' => 0, 'AUTOSHIP' => 0, 'PRODUCT_GROUP' => -1, 'THUMBNAIL' => '', 'IMAGE' => '13139_694.jpg', 'ALSOBOUGHT' => [], 'RELATED' => [],  }, 
    '13140' => { 'REFERENCE' => '13140', 'NAME' => 'DRAPER Five Extra Coarse Grade Aluminium Oxide Sanding Discs', 'PRICE' => 96, 'MIN_QUANTITY_ORDERABLE' => 1, 'MAX_QUANTITY_ORDERABLE' => 0, 'OUT_OF_STOCK' => 0, 'DATE_PROMPT' => '', 'OTHER_INFO_PROMPT' => '', 'PRICING_MODEL' => 0, 'TAX_1' => '101=2000.00=0=', 'OPAQUE_SHIPPING_DATA' => '0.055', 'ALT_WEIGHT' => '', 'SHIP_SEPARATELY' => 0, 'SHIP_CATEGORY' => '', 'SHIP_SUPPLEMENT' => 0, 'SHIP_SUPPLEMENT_ONCE' => 0, 'HAND_SUPPLEMENT' => 0, 'HAND_SUPPLEMENT_ONCE' => 0, 'SHIP_QUANTITY' => 1, 'COST_PRICE' => 0, 'EXCLUDE_FROM_SHIP' => 0, 'ASSEMBLY_PRODUCT' => 0, 'STOCK_AISLE' => '', 'STOCK_RACK' => '', 'STOCK_SUB_RACK' => '', 'STOCK_BIN' => '', 'BARCODE' => '', 'REPORT_DESC' => '', 'PRICES' => {

这里有3个项目。它们以类似'13138' => { 'REFERENCE'的字符串开头。和字符串结束前的类型相同。我怎么把这些部分分开？在

{cd2>试过了。但不匹配。在

Answer 1

为什么不直接用=>替换:：

    'CUSTOMVARS' :
        {
        },
'NO_ORDERLINE' : 0, 'AUTOSHIP' : 0, 'PRODUCT_GROUP' : -1, ...

并使用^{}计算它。它只计算文本，而不计算可执行代码，因此不需要进行清理（对于过大的输入，可能需要保护）：

ast.literal_eval(node_or_string)

Safely evaluate an expression node or a string containing a Python expression. The string or node provided may only consist of the following Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.

This can be used for safely evaluating strings containing Python expressions from untrusted sources without the need to parse the values oneself.

^{pr2}$

有关只替换=>外部字符串的信息，请参阅 这个答案是：

• Replace whitespace outside quotes using regular expression

给定的文件包含哈希本身之外的其他标记。中的regexp ^上面的{}去掉了多余的标记：

\s+=\s+      # This marks the = before the start of the hash
({           # Capture the first {
  (?:.|\n)+  # This matches all characters.
             # The (?: is to prevent capture-inside-capture
})           # Capture the last }
;            # This is not captured
